Dear Forum,
If I had any hair I would be tearing it out. My normally reliable Mobylette AV 42 started to misfire. I started with the usual cures - thoroughly cleaned the carb, plug etc. Had the HT coil and condenser (new) checked and fitted new plug and cap. Changed the cable from the LT coil to the HT coil. Took the engine out of the frame and ran on bench - swapped carburettor with a known working one. Still misfires. When observing the plug while spinning the engine with a drill the spark looks constant and consistant. The exhaust is OK. Having checked the HT coil and condenser Mark Daniels is now checking the LT coil. If that comes back OK (which I expect it will) does the forum have any other ideas??
