Not running dual carbs, just stock Rochester "B". Have just replaced with a fresh rebuild from Advance, but wanted to figure what else may be problem before I tried starting it again, for fear of messing something up internally.
"Runs like crap" means... after adjusting the carb, and timing it will run smoothly for maybe a half hour or so(idling on the driveway). Then it starts to run rich, sputer, miss, blow black sooty smoke, you know, "run like crap". I can wait til the next day, when engine has cooled completly, and immediatley upon start up, it will "run like crap", just like it did when it ran warmed up the day before. At which opoint I get disgusted and let it sit for a month before I go fiddle with it some more to get it to run smooth again, only to have the same scenario played out. I did replace the heat riser spring, and the heat riser moves freely, but I have never seen the spring or heat riser do anything other than just sit there. As I'm in Florida, I dont know if the heat riser actually plays that big of a factor, but I have manually moved the riser while the engine was "running like crap", and it didnt make any difference. I have tested the Vac advance, it holds 9" as long as I want it too. The dizzy is clamped down tight. I am running a Pertronix module, but put the points back in just for the sake of testing it. Same thing either way. Maybe I should just try starting with the "new" rebuilt carb, and see what happens?
