Hey, this is the most interesting post I've seen in days - actual roadster
content!
Anyways, from your post I gather you've recently done some work on the
engine - did you r&r the head? If so, perhaps your cam is one tooth out? It
sounds to me like there's something up with the ignition advance curve -
i.e. too advanced at low speed (and maybe too advanced at high speed as
well, but it's closer to where it should be).

BTW, the battle on the Roadster continues... new gaskets; no change.
Re-wire; no change. Tried a points dizzy, could not get it to run (yet)...
put the EI back in, fired immediately. Car runs hot at low speeds (over 220
degrees) with a serious rad, good thermostat, etc. If I run the crap (I
mean 100 + mph) out of it it cools down to 190 and has plenty of power... go
figure. I must be lean on the low end, but changing to richer jets makes it
worse. Hoping a friend with an exhaust analyizer will be able to look at
it. Compression is 155-165 all 4, lower than recently recorded 185-190, but
no sign of head gasket leak. I have NEVER been so stumped by a car, and
this is a simple engine. I'll admit, I am so mad at it right now I have had
thoughts of selling it. There, I said it... are you listening to me
Roadster Gods? (maybe that will help...).
