Presidential Ramblings, by Craig Madsen

Fall finds me scrambling, four out of five weekends out of state - Parents day at son Brian's College, several weekends helping my folks get moved and dragging more Triumphs home and a Saturday installing equipment in Illinois for my employer... I heard the color tour was awesome and graced with a plethora of marques in addition to our own, How fun! I haven’t heard about the Halloween Party but I'm certain too, it was a smashing success.

November will find us at VP John Lamberg's residence on the 20th. The club will give the dogs & brats one more go around this year. Buns & condiments will also be provided.  Bring a beverage of your choice and a side dish if you'd like, we never seem to go hungry do we?!

I'm looking forward to this years Christmas party (Dec.7) I'll be hammering out a formal invite to our friends in the MG & Healey clubs. Santa is working on a surprise for all those hard working elves this year so be sure get your money to Bonnie so we can get the number of attendees to the folks at Bevo Mill.

This years party will also include the "Rob Your  Neighbor" gift exchange, gifts not to exceed $20.00 in value, you may bring as many or as few as you like. I'll see if I can commandeer Carl to make sure everyone that brings a gift gets a ticket. Don't miss the fun!

I've learned this year that I can't save every Triumph automobile that I see, nor is it healthy mentally to acquire an excess of these vehicles! There needs to be a thinning of the heard. So the first to go will probably be the blue coup followed by the burgundy spit. If anyone is interested let me know. I hope to next year be able to focus a little better - more work done on fewer cars, that's the goal! That being said, all those closet presidential wanna be's, this is the year (March) I'll be passing the gavel. In the interest of keeping things Fresh & entertaining, I believe it's the right thing to do. One of the reasons for not permanently picking a meeting venue in the last 2 years is in the interest of our membership which is scattered across a large area. Another was that not everyone likes everything about any given restaurant, food/ beer/ location/ etc. One thing the majority seem to enjoy is our gathering at the Bevo Mill for Christmas so, I hope that's a tradition we'll carry forward! I'm not saying I won't do it again, I just don't want things to get stagnated. We've got a great, growing membership which I would like to increase. If a position was available for a Membership Chairman, I might be convinced to take on duties in that capacity! Remember that car show I wanted to get started at lake Ozark? Maybe I can get started pursuing that.  Anyway -

The Fun will continue! Winter brings the Polar Bear Run, countless restoration (full & partial) projects, I'm still working on getting Ted here for an informative chat. But for now, take a breath, another look at the leaves, and get ready for the Holidays!

Hope to see you at Johns!                                                   Craig Madsen

Continuation of SU Carburetor Tips,  Introduction note by Creig Houghtaling

Jim Taylor is a retired design engineer with over 40 years experience rebuilding SU carburetors and fuel pumps. The following is a continuation in a series of articles on the most common problems that Jim has observed in carburetors that come to him for service.

The following article is reprinted here by permission from Jim Taylor.  Please refer to the April SLTOA newsletter for Karl Schmitt’s introduction of Jim.  There are several articles that will be reprinted over next several months in this newsletter.  Make sure you keep the April and May copies available for reference back to the detailed SU drawing.


Unfortunately, the people assembling aftermarket carb kits don't always appreciate the significance of the original specifications, or in some cases just have poor quality control. Two items come to mind:

1. On the H series carbs the upper jet bearing copper washer is supposed to be 0.016" thick. Many aftermarket kits have this washer 0.025" or even 0.033" thick. This holds the complete jet assembly down farther away from the needle than intended and defeats about 1/2 turn of the mixture adjustment nut (ability to lean out).

2. Jet orifice sizes arc 0.090", 0.100", and 0.125" in diameter. I have made a set of pin gages to check these orifice diameters. The typical smaller gage is 0.089" diameter on one end, is 2" long, and tapers uniformly to 0.090" on the big end. When the small end is inserted in the orifice the gage ideally should become snug about 1/2 way up its length. If it slides all the way through I don't use the jet. An orifice 0.0005" too large, and many are, may give you trouble in leaning out the mixture enough.


On the HD series carb the throttle plate is completely closed at idle with slow running being controlled by a needle valve by-passing the throttle plate. The choke lever actuates a fast idle cam which opens the throttle plate slightly during cold starts. The fast idle screw should have about 1/2 turn clearance from the throttle lever when the choke is in the off position. Do not set normal idle speed with this screw. Use the slow run needle valve.


The virtues of Grose-Jet float valves were extolled in a previous article (#VIII.) The standard SU-301 Grose-Jet used for essentially all of the SU carbs, except the HGF series, has an orifice of 0.084" diameter. This is satisfactory for most normal use. For racing applications where full throttle accelerations or full throttle high speed runs are needed with the bigger carbs such as HD-8's, an optional 0.099" orifice is available. Specify SU-301-0.099".


The inlet flange on SU carbs normally has 4 holes drilled in it. The two holes on the center-line are for mounting the air cleaner. Two holes slightly above the center-line are vent holes bringing atmospheric air to the underside of the piston. These vent holes must match with holes in the air cleaner shell or mounting plate. Since many of the pancake air cleaners are symmetrical, they can be installed upside down thus blocking off the vent holes. Be sure air cleaners are installed right side up with vent holes matching.


The HS series carbs as used on BJ-7 Healeys and most Sprites, Midgets, MGB's have a small rectangular lug cast on the side of the body. This lug engages a slot in the float bowl rubber grommet to determine the tilt of the float bowl. Due to accident or rough handling sometimes the lug is broken off. It may be replaced with a 5/32" diameter x 3/8" long roll pin. Drill a 5/32" hole x 3/16" deep, drive in the roll pin and set in LocTite for good measure. It works adequately.


Throttle return spring clips, interconnecting throttle shaft "W" couplings, and interconnecting shaft levers are all anchored to their respective shafts with a pinch bolt. The clips, couplings, and levers all have a recess to retain the pinch bolt head and prevent it from turning. Always install the bolt head in the recess with the nut and plain washer on the smooth side of the fitting. When orienting the fittings on their respective shafts always have the nut facing up so it is readily accessible to a nut driver for making synchronization adjustments on the carburetors.


On the H series carbs, float bowls are mounted to the carb body with a single mounting bolt. The float bowl will pivot around the mounting bolt. Correct orientation of the float bowl is at right angles to the carb body. Fiber washers used with the shouldered mounting bolt will essentially lock the float bowl in place. Rubber grommets used with the later straight sided mounting bolts will allow the float bowl to inadvertently be moved. Don't let the bowl be swung too far towards the rear of the carb or it will foul the spring return clip on the throttle shaft. Carb kits frequently contain both fiber washers and rubber grommets to accommodate either type of mounting bolt. Don't intermix fiber washers and rubber grommets on the same bolt. You may not be able to compress the rubber sufficiently to get the fiber washer to seal.


The HD-8 carbs fitted to the BJ-8 AH are equipped with teflon SLEEVE bushings. These minimize shaft wear and are easily replaceable. About 90% of the BJ-8 carbs I see have shaft wear less than 0.001" and thus do not require new throttle shafts. Replacement of the teflon sleeves will restore a good fit The sleeves are furnished flat and must be rolled, much like a cigarette paper, for installation. The sleeves are kept from walking on the shaft by split retainer rings on each side of the sleeve. It is imperative that the person disassembling the throttle shaft assembly knows that the split retainer rings are there and must exercise diligence to assure that the rings do not fall out and become lost The split rings are not available anymore. Many of the replacement teflon sleeves are not precisely cut (they are too large) and thus the edges will overlap each other or the retainer rings causing binding. The proper dimensions in the flat state are 33/32" on the long edge and 17/32" at right angles to the long edge. The sleeves may be trimmed with a straight edge and an X-Acto knife.


The helical throttle return springs used on "H" series carbs and HD-6 series carbs are anchored to the body with a brass spider-like anchor having five fingers. The outer end of the spring is anchored to the shaft with a clip and pinch bolt. On the "H" series anchors the two long fingers must straddle the throttle stop lug on the carb body. On the HD-6 series anchor, which is slightly larger, the wide gap between the lingers goes over the wide lug and one long finger must bear against the thin lug.


Jet levers on the HD-6 carbs are connected through a threaded choke rod with a fork or clevis on each end. The rod length must be adjusted by screwing the fork ends in or out so that with the jet levers in the full off position the clevis pin will fit easily through the hole in the lever and fork end. The fork end is formed out of fairly thin metal so the threaded hole in the fork end has only about three threads. It is essential that the lock nut be tight against the fork end to prevent vibration from ruining the threads in the fork end and on the rod.

1972 Triumph GT6 for sale  --  This is a car that my father in law and I did a rolling restoration on about 7 years ago. The motor is rebuilt with higher compression pistons, fast road cam, rebuilt carbs and a 6-3-1 stainless header and stainless exhaust. The car was painted and all rust repaired with new steel welded in place. I have pictures of the restoration and most of the reciepts for the parts purchaced. The car has fresh tires and brakes. The car is mechanically solid.
The car comes with lots of spare parts. There are two engines, a transmission, two differentials, starters, alternators, complete front and rear suspension, spare carbs, complete spare exhaust, windshield, doors, rear hatch and glass, wheels, guages, brand new rotors and boxes and boxes of odds and ends. Way more than I could list here.
If you have a spitfire use the spare parts to make yourself a Spit6.
I love the car and hate to see it go but I have too many other toys and some looming bills. It has always been in the garage since the restoration. The last few years have been in a heated garage. For the car and the truckload of spare parts I will take $6500 or best offer.
