engine miss
I have a Yamaha g8 with an engine miss. i just rebuilt the motor 2 months ago i port and polished it cut the head bored the carb jet air filter and exhaust mod. it has ran great until about a a week ago. it misses all the way through the throttle up. i know some about these carts so i have already tried cleaning carb and fuel pump i made sure fuel filter wasn't clogged and its not.spark plug looks to be burning rich lots of black. the only thing i can say that it might be is the magnetic pick up behind the flywheel. the only reason i say this is because when i rebuilt it that looked beat up and dirty but i was in a hurry and ran it any way. any input on this would be great thanks.

Re: engine miss
What happens when you put a fresh spark plug in it?

Re: engine miss
Miss and black plug sounds rich try it with out the filter. The warmer weather may have tiped you over the jet bore.
