Just drowned my "new" CEN NT16 engine in wd40. Everything was going fine, engine has a lot of compression, basically new, but now, I put in the clutchbell and the screw that holds it, but with loctite. That loctite probably created some sort of pressure when I screwed in this screw, because there's no other way it can flow, and it locked itself together with the screw. Screw head stripped, tried turning it with a monkey wrench and the screw head fell off. Please help
