Been having trouble starting up my "mystery pocketbike engine" I bought on ebay. It had been sitting for years, so I installed a new carb and sparkplug, then went on a goped site to pick up helpful tips. Some riders advised to check ignition coil gap with a business card, so I removed the pullstart and cover and checked that.
Absolutely no spark at the plug, so I pulled the flywheel to check if the woodruff key had sheared off and moved the ignition timing.....
The flywheel had the slot for the timing key, but there was NO TIMING KEY!!!
Then I checked the crankshaft snout...and there was NO SLOT FOR TIMING KEY!!!
Now how the heck do I set timing? There are a few homemade scribe lines near the flywheel's magnetic pickup. They might be the new timing marks that align to some spot on the engine block. The crank snout is a tapered shaft, so that might keep the shaft from spinning off and changing the timing. The crank is an aftermarket "stuffed" crank with extra counterweight for high revving.
This engine has a high-output aftermarket coil/pickup. It should provide a powerful spark, but has nothing. What I will do is keep moving the flywheel on the crank snout until a spark is produced.
Any ideas, fellas?
