Yeah its those dam stock carbs mine stuck all the time till i got rid of them, one time belive this story or not( i got witnesses) i took me shee for a spin around the yard so i come back up to let my freind take it around once so when i put it in nuetral the idle just went nuts it went to id say 11000 rpms and was just screaminso i hit the killswitch it didnt do a dam thing, shut off the gas did nothing, pulled the spark plug caps off -this is where it really gets me it did nothing, by this time my freinds were runnin like hell becuase we all thought it was gonna blow up, so all i do is touch the throttle and it idles down then dies. Anyway even tho there was no point in thelling that story i have nothing to do
