Definitely check for bad connections and for 4 good sparks but also check, clean and reset or renew the plugs. QL77JC4 gapped at 0.030" now recommended type. Inspect HT leads. |

hey Richard.....Try this.. Next time out,pump the primer bulb up hard and hold it while you try to get back up to speed...If this does it, look at your fuel filter..fuel line to see if you see/smell gas...If the problem is still there, good chance the high-speed jets are fouled, and the carbs need to be removed and rebuilt... |
