I am not green, and did the carb twice, same issue, FINALLY, after I replaced the fuel line and petcock, I put a new plug in too, VIOLA! RUNS perfect- so was it the carb/line/fuel cap/ or PLUG????? Evidentely the PLUG, It started and ran fine, for a few minutes, but once hot, it quit firing. EVERYONE NEEDS To keep this in mind BEFORE you tear into one of these HONDAS.
