No rev limiter except the screw on the throttle. I have painted a mark where it's supposed to be and it 's still at that mark. This all has me wondering if weak spark could cause this issue.

I have a 110 ATV which started fine yesterday. Today I go to start it and it only starts with the throttle wide open and then runs at low RPM, Unit is getting spark. Would apprecate any help I could get. Unit is a Chinese ATV.
