[TR] Idle Problem

[Bob Labuz]

Bill,

Sounds like it could be a vacuum leak. Maybe try to spray some wd40 
where the carbs are attached and the intake manifold to see if you can 
detect a leak.

Also check the dash pots to insure they are filled with 20W or ATF. Make 
sure the carb pistons are not sticking.

I use that blue gasket stuff in addition to the stock gaskets when 
attaching both the intake manifold and the carbs to the manifold.

All 3 engines purr at around 750 to 850 RPM when warm.

Bob
