Presidential Ramblings, By Craig Madsen

Like most of us I'm behind on my projects. The goal was to either to deliver the orange TR7 to my Father over the holiday , or take it to Champagne, neither occurred. The car was willing to make the trip, but I wasn't! It will find it's way back to Iowa next weekend, but that means I won't get to go with John to Louisville. Very frustrating.

I'm overdue for some TR comradery & enthusiasm. Hopefully I'll procure that at our June picnic. I'm excited about our new location. Creig has promised us our cars can be parked in the immediate vicinity of the pavilion.The picnic date is an exception to our 3rd Tuesday of the month rule and is on June 12th. This event is always fun & promises to be even better this year. Iknow it's a week night but if at all possible please try to make your presence know - you won't be disappointed.

Next scheduled stop for me is The Roadster Factory Summer Party. I don't know what I'm taking or how I'm getting there, but that is the plan. I'm sure there's something else locally going on before that so check out the upcoming list of events & pencil yourself in! - maybe I'll see you there. At the very least I'll look forward to seeing everyone at the June Picnic. †††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††† Craig Madsen

A Day on the Farm with Mel & Gail Parentin, Saturday May 19th,By Creig Houghtaling

The weather was perfect for a day in the country.Mel and Gail have a beautiful farm just west of Bourbon MO.They invited SLTOA club members and others to enjoy it with them.Mel keeps several acres of hill-side mowed making a wonderful shooting range.Several people enjoyed shooting a wide range of vintage and modern firearms.To add to the entertainment, some of the targets were filled with exploding ordnance that sounded like a large caliber cannon when hit.Boys donít quit being boys just because they get old!

Woodland trails and fishing in a private pond were enjoyed by many.At lunch time, Mel treated everyone to his very special recipe pizzas.Thank you Mel!Thank you Gail!I am sure everyone present enjoyed the day as much as me!

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 Schmittís 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.

SU Carburetor Tips,By Jim Taylor


In disassembling old SU carbs, the inlet banjo bolts are probably the most difficult fittings to remove. Corrosion occurs between the steel threads on the bolt and the aluminum threads in the lid. The metal in the lid is a thin domed shell without much strength in resisting torque. If the bolt is stuck and brute force is used in turning the bolt you probably are going to break the lid. New lids, if available, are about $39.00 so it behooves one to proceed cautiously. A technique I have used with about 90% success rate is as follows: Remove lid from float bowl. Clamp a 7/8" open end wrench in a vise. Place the boss which the bolt screws into, in the 7/8" open end wrench. The metal in the boss is much thicker and stronger than the lid proper. Apply a firm steady torque to the bolt head with a 13/16" socket in a 1/2" drive rachet handle. If it still doesn't want to turn, squirt an aerosol penetrating-oil through the float valve opening in the lid. Have a colleague gently play a torch on the outside of the boss while you continue to apply torque to the bolt. Aluminum expands more with heat than the steel, thus facilitating the removal. (Photograph optional)


The diaphram jet assembly item #10, figure 10 is a sound design concept. When in good condition it doesn't leak, the jet is free to move without friction in the jet bearing when you pull the choke, and the assembly is protected from external damage. Unfortunately rubber products deteriorate with age and exposure to fuel. If your jet diaphram is over 10 years old it quite likely is hard and stiff and doesn't want to flex properly when the choke is pulled. It eventually will crack and leak. When replacing a jet assembly it is a good idea to have replacement jet return springs available item #12, figure 10. The springs sit down in the lowest part of the carburetor where water collects and will frequently be badly corroded.


On HD carbs, breaking loose the jet bearing locking nut, item #16 figure 10, may be troublesome. After removing the float chamber, jet, and jet housing, access to the locking nut is attained. Squirt an aerosol penetrating oil around the nut head. Rap the head of the nut sharply with a hammer and 3/16" punch around the periphery of the head in about a dozen places. A properly sized Whitworth socket and ratchet handle will then usually easily break it loose.

Carbs that have been in storage in a coastal atmosphere for long periods may present special disassembly problem. The piston may be stuck in the suction chamber and also in the body of the carburetor. There is not much access, nor much way to apply any force. After removing the jet bearing locking nut as described above, the jet bearing, and the suction chamber screws, it is possible to insert a 3/8" O.D. steel tube from the bottom through the hole for the jet bearing and drive the piston along with its suction chamber out of the body. Once removed from the body, the piston may be driven out of its suction chamber by inserting a 5/16" brass bar inside the hollow piston rod in place of the damper. All impact in both steps is on the steel piston rod base and thus does not damage the soft aluminum parts.
