Bud,
Could be the opposite of fuel starvation...flooding. Once you get past 2000
RPMs theres enough air to compensate for a little extra fuel...at lower RPMs
the mix is more critical. I think checking the float bowls for particles that
might be causing the fuel needle valve to stick might be a good idea.

Subject: [TR] TR6 stumbling at low rpm
I've been driving my rebuilt 75 TR6 now for about a month and have put on
about 500 miles. Overall, I am very pleased with the way it is performing. It
starts quickly and idles well. In the 2000 - 3000 rpm range, it has more than
enough power, so driving winding roads is a blast. The only problem I am still
having is accelerating form a standing start or cruising at a low rpm (like in
the neigborhood). As I ease off the clutch and apply the accelerator, the car
will stumble. It has never completely stalled and died. As I slowly
accelerate, it will continue to stumble or miss, until it hits about 2000 rpm,
then it will take off like it should. Just criusing at around 1500 -2000, it
will stumble, also. It is acting like it is leaning out too much, but I have
checked the dashpots for oil and checked for vacuum leaks with propane. That
appears to be OK. I have not checked my float bowls yet, but that is next,
unless someone suggests something else. I am thinking that the floats
may be too low, causing fuel starvation at low rpms. When the pump is
operating at higher rpm, the fuel may be being pumped into the carbs fast
enough to keep up with demand. Does this make since?
Thanks,
Bud Trussell
