I recently pick'd up the motor,fired it up to find it has a idle/low speed miss that dissapears when running faster than idle,it has good holeshot and no stumbling at speed.brought it back home ran it on the muffs and lightly squirted carb cleaner "fine mist not full spray" into intake and the miss was less pronounced stop spraying it would return.checked all wiring on the motor everything looks good,but i do get a little tingle when touching #1 plug boot.i'm assuming this is a fuel issue,but would like to know where everyone would start in fixing this problem. Thanks!!
