would too lean make it backfire at low rpm when just trying to idle?
also timing is tdc and when i move the distibutor a little each way it doesn't make it get better.
any suggestion on adjusting this carb,,holley 4-barrel 4110, vacum secondaries.
also when trying to start, it backfired through the carb and blew both caps off my valvecovers.
