I'll clarify one thing. I had to pull the glow plug on the engine that was sent to me and the Cumbustion Chamber did move and it was a bit of a bear to get the glow plug back in there. Also, the glow plug that was sent with the engine was nearly impossible to pull the two strands out, in fact, when I tried, it let off on the end and made the glow plug useless. We ended up using a McCoy #9 and no issues related to plug.

By the way Justin, still don't ahve your address [email protected]
