I'm one who doesn't know what I'm talkin about... we tried and tried and tried to get a 91 FX to run but the darn @#$$# bubbles would not go away!!! soa friend lent us another .91FX to try on the GP Super Skybolt wihout success... bubbles AND overheating.. changed carbs, cleaned carbs, sealed remote needeles no good...
Bought a 91 MAgnum XLS ... as good as or better power than the FX's staight out of the box... idels reliably no deadsticks...
and two more EXpensive paper weights around the shop...
Regards,
Patrick
