Ok me and my friend thought we fixed this but to day it started to do it again?? We think it could maybe be something electrical?? The weird thing is when I activate the trim controls it like sucks the power from the engine?? This only happens when the engine is warmed up and starts to sputter whats up with that?? It seems to start acting up when it is warmed up or has been riding for a while. Any ideas?? It would not be nothing with the carb would it, runs just fine at idle and full out, until till later?? Well when I give it allot of throttle quickly it like chokes out quickly and then goes and revs up... is that normal. Can you guys help me out here!!! Thank you!! I am going to get a service manual tomorrow; you guys think that will help...??
