i put a new cylinder/piston/rings on my 1981 peugeot 103. it started with starter fluid. i drove down the street. when i let off the throttle a bit, it sounded like it stopped running. the noise got quieter, i slowed way down. then i gave it full throttle. after a second of lag, it picked back up again, the noise sounded like it was running again, i accelerated. i tried to keep it at full throttle, then it died. i pedaled it home, there was some oil on the spark plug. oil was leaking from the base gasket. it started again a few times, but only with starter fluid. i could keep it running for 30 seconds max, then it would die. then i'd take out the spark plug, clean it off (sometimes it was covered in oil, sometimes not), spray starter fluid in the cylinder, start it up again...
so what could be the problem here? why wont it stay on? why are the plugs fouling? why is does it seem to be flooding?
here's some more info:
i have a dellorto carb with a #58 jet in it (2 holes in the airbox, took baffle out of exhaust)
i'm pretty sure the base gasket is bad. i can hear a pfft...pfft from the base as the piston moves up and down.
gas is NOT pouring out of the exhaust. there's just oily stuff leaking from the base gasket.
