Hey guys bought a fresh predator motor and first thing I pulled the govenor and guts out, put an ARC Flywheel on, Higher tension Valve springs, and an air filter and jet kit. But I did not touch anything else. Now I went to break it in the other night and oiled it, and as soon as it hits compression it just gets EXTREMELY hard to pull, so I can't really get it up to speed. I tried using an impact on the flywheel and that won't budge it. Cam is in right I know, I have heard things about the compression relief valve (maybe that idk) . I took the plug out and I can spin it by hand very easily like a bearing. The valves are adjusted right too. Any ideas. Its like the compression is too high. All I managed was a pop once, but even with starter fluid it doesnt fire.
