Ok, could still be some air in the cooling system. That might account for one cylinder getting hot so quickly.I don't think it had the time to circulate. it was on for 2-3 minutes before I shut it off to ask you guys. I'll have time to run it tomorrow and check the temps. hopefully it'll get better
I wouldn't pull the carbs until we know what's going on, if it's running on both cylinders now, the carbs may be ok.
