i have a 66cc grubee skyhawk engine, the jug crapped out, i swapped it with a new one, i put one gasket because i only had one, but originally it had two.
at open throttle it seems like it bogs out, however i put a smaller jet, and then it died out when i revved it, or just used it at all after turning off the choke. i replaced the entire fuel hose, got a high flow petcock valve, and new fuel filter. (after having issues not before)
ive tried jets from #80 to #55 in increments of 5. id rather not have to take the jug off, does it seem possible that a single gasket would make it bog like that? it almost sounds like its 4 stroking, if i apply the throttle fully(or more that 1/3 of the way on flat land) it starts firing weird. (with a size 60 jet)(dellorto sha carb) would that single gasket really cause this kind of problem? also, gas and oil keep winding up in the intake.
I assume the ports are not lined up right or the timing is off or something. i have two gaskets now, i just dont want to go through the effort if im totally off base. or if i can just get a jaguar cdi and tune it to the way the piston and cylinder is now. (dont really care if theirs oil in the fuel filter to be honest, just want to go at a decent speed.)
