So my 66/80cc flying horse kit arrived all parts were there in good condition for the most part. They sent me a slant head instead of flat head I ordered. My tank had a slight ding and a slightly skewed mounting bolt no rust inside.
Gonna put jb weld at the mounting studs weld to prevent possible leaking. Gonna replace all kit studs with BBR engine studs and replace wheel mount studs. One possible issue is there's a visible gap between head and cylinder body head is not flat and smooth head and cylinder sides have a noticeable combined gap like 1/2mm to 1mm. They're not straight on either side and the original studs are really tight but the gasket isn't flat and definitely not air tight. The gasket is aluminum. The 2 sides don't contact each other either but the studs are tight.My Questions #1 Could it be possible they weren't tightend all the way at factory. #2 how do I remove the unevenness on both sides? Could I sand them flat and smooth? Then use a torque wrench? Please let me know soon. I want to deal with this now rather then later. I'm willing to purchase torque wrench and sanding supply's. Thanks,
Joshua P.S it seems head is backward? Plug hole is facing to back of engine not forward. Which way should it face? Thanks.
