I've a 1978 Peugeot 103 that doesn't seem to want to run anymore.
It ran fine last summer, but when I took it out last weekend I couldn't get it to run properly. After several hours of fiddling with it I can get it to barely run (i.e. it'll fire and spin, but eventually die if I don't keep pedalling) --it will not run fast and it certainly won't idle with or without the choke. It fouls plugs with thick black carbon in seconds (i.e. 20 seconds of pseudo-running).
Here are the Peugeot's vital stat's:
1) The timing is dead-on with respect to the points (1.9mm before TDC). I've also tried retarding and advancing the timing from spec with no improvement.
2) Compression is 150psi.
3) I've decarbonized the cylinger, piston, exhaust, and ports.
4) I've cleaned the carb thoroughly, twice.
5) I've disconnected the wiring harness from the engine in case the problem is a short somewhere --the engine runs the same.
6) I wanted to remove the flywheel to adjust the stator advance, but I do not have the proper tool to do so. Since the moped used to run perfectly last year, I assume that the stator advance is probably fine.
7) I've cleaned the points as best I can.
8) The fuel mix is 50:1 as per manufacturer's specs.
9) The air filter and air box is clean.
I've all but run out of things that I can think of!
Can anyone out there suggest anything I should test/measure/try to get this engine running? If I need to split the crankcase or pull the flywheel, can someone suggest a place to get the special tools for this?
Thanks in advance,
