Thanks again. I have multiple issues with most things but my life is never dull. I think when I die I'll go straight to Heaven and not have to spend any time in Purgatory becaue I'm paying my dues as we speak. I don't have the Haynes manual but I bought a CD on eBay though it's hard to use. I still can't find the spring and valve previously mentioned. I turned my inspection mirror in every possible direction but don't see them. Theoretically, these procedures sound easy but I still can't get any pooling of fuel to show. I want to check the chain since I have the whole front of the engine apart. I think that would make it easy to replace if I have to. I'll check the archives for chain stretch. Fisherman, I would sure like more instruction if you don't mind.
