[QUOTE="El Seed, post: 21233, member: 17072"] Thanks for the reply, Comben. Though my situation was vaguely stated, wise advice from such as yourself seems to inevitably point back to the tranny seals. Tried every jetting combination, bracketing rich and lean -- behavior the same in all cases at high revs. Have personally licked the carb. clean, and everywhere else fuel travels. EasiStart is a good procedure for testing inlet boot -- indeed old and hardened. Could be a leaker. Tested ignition circuit to best of my ability -- do magneto pickups malfunction at higher revs? Don't have a timing light or such for adequately testing the spark. Anyways, 'Survey Says?!' -- Ding!: Seals deteriorate in an engine at rest. Will pursue this angle. Thanks again. [/QUOTE]
