Went for a good ride last weekend about half way through starting running real rough couldnt full throttle it would almost die at full throttle had to keep low rpms to get it home but still rough at low rpms any ideas?

 

Was it back firing alot by any chance??? It could be the parking brake it has a thing to it... It will choke the carb when you hit the gas there for wanting to kill your engine...Just a thaught, I had it happen to me and from what you said it kinda matches the problem I had.

 

little bit of dirt might have got into the carb, maybe an old plug also, or the parking brake sensor

 

Finally started tearing down the motor this weekend the exhaust valve adjustment became loose and totally backed out I cant belive it didnt wreck anything it felt like the carb got shitty what a relief to find an easy fix. hope this helps someone out in the future
