I recently put a new timing gear on, dropped the pan and cleaned it out. replaced all the gaskets put it all back together. And re-did the timing. My 1929 Backfires at the top of each gear, at what feels like top speed at each gear. And the other day it backfired shortly after shutting it down. I havent owned it long, and i have been driving around with the spark advance all the way down after startup. But i was recently told i should be driving with it 1/2 way down just normal driving, and 3/4 the way down at faster longer driving. But could this backfire be from carb settings? Or maybe my timing isnt spot on? Or could driving with the spark advance lever all the way down do it? Im new to the Model A seen, dont know all that much yet. Im sure there is already a thread on this but i couldnt find it through the search. sorry if so.
