OK. Unless the advance mechanism is gummed up, timing is probably not the issue. Might just be thin in that area. The exhaust crossover passage is to heat the carb base to prevent icing up. Due to the pressure drop across the carb venturii, internal carb temperature can drop below freezing, and moisture in the air condenses and freezes inside the carb.
