Bud,
Did you check for a VAC leak around the rocker cover? I had the same prob with
my 76 and it took time to figure out the problem. The cover sometimes fit a
bit offset because the studs are not perfectly aligned. Then the gasket twist
inside and you dont see it from outside. Now when I put a new gasket, I put a
thin layer of sealer inside the rail in the cover, put the gasket in and tape
it until the sealer is dry. After, a bit on the other side of the gasket and
just a drop around the stud washer. I found that it stopped the leak and the
miss.
Hope this will help.

Objet : [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
