I'm going to need some help with the new go-II ho. I cleaned it out reassembled/ re-oiled/installed new glow plug/preheated/engine is froze!!!!!!!!!!!!!!!!!!!!!! Tried to turn over thought it was going to fire right up[sounded like it] I used my snap-on 3/8th drive breaker bar with 8mm socket on it to get it to go around. Thought for sure I lost a c-clip. Taken engine apart nothing,no shavings no c-clip off piston not scored/sleeve great no lost glow plug tip. Only thing I can think of is the front bearing seems notchy in 1 spot but I don't think that would cause engine to lock in place tdc. Or is it that the engine is just that tight? any one have any trouble? I am going to put it all back together and try again.
