my motor will start and idle but when the throttle is engaged the motor will not pull the weight of the cart. what may be the problem? is it possibly the voltage regulator,the sparkplug coil or a carb. issue? please give me all possible reasons so i can troubleshoot the issue. thanx,bostonadams2

 

if the motor revs up, check your clutch. does it smell burnt? the clutch may need adjusting. refer to your owner's manual. if you don't have one, holler, we'll see what we can come up with. sorry, not familiar with sunl. i presume the 110cc is a forward/reverse only, right? not a L/H/R?

 

it is a forward only. it has no reverse.
