Wish I could tell you for sure but not positive if you have lined everything up at tdc should be fine. Have you also checked valve lash? Maybe they are a little to loose. I'll do a little research and see what I can do to help out

Ignition timing set correctly etc? Maybe to far advanced? Cannot tell whether coming from low end or top?

Thanks a bunch for the information gathering you have done by far got a lot further than I did in days of searching. Still of to me that there is such little info about these 4 wheelers. Almost like they don't exist. Thanks again
