ok... finally got around to working on my '59 av88, replaced and readjusted the throttle cable and decompression lever cable. after doing that, trying to start it was a little more successful than before - the engine looks like it wants to turn (the flywheel will barely start to turn, maybe 1-1&1/2 spins), whereas before it wouldn't start to move at all. however, it still doesn't start and it doesn't sound like it's trying to start at all (no sputtering or anything).
a funny thing that happened is after about half an hour of trying to start it yesterday it felt like it had lost compression - there was almost no resistance when turning the flywheel by hand. i went back out this morning to try again and there was plenty of resistance, so i'm assuming the compression went up again. would this be caused by a leak somewhere or something?
i put new gas (4 oz. of two-stroke oil per gallon) in yesterday before i tried to start it up. i know gas is getting to the engine because i tested the fuel line where it meets the carburetor - i'm sure the entire fuel line could use a good cleaning but i know this moped has run before. when i bought it in november it would start but you had to use a power drill with a square bit inserted into the right side of the flywheel to start it. unfortunately, i don't have a power drill, couldn't take one with me everywhere i went, and would like to get this thing to start the way it's supposed to.
any suggestions? your input will be very much appreciated... thanks!
