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
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. I know 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

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.

SU Carburetor Tips, By Jim Taylor
II FLOAT LID INLET BANJO BOLT REMOVAL
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)
III SU HD
JET ASSEMBLIES AND JET RETURN SPRINGS
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.
IV FURTHER DISASSEMBLY TIPS - SU CARBS
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.
