Actually the 1st one I had issues with ran perfectly fine today once I put a different rated glow plug than what I was originally sold for it. I actually found a hobby shop with WAY more knowledgeable people working in it than the one I was first going to.

and yes the 2 that had issues are the flat tops and I already started looking for a replacement for the one that won't stay on at all. I found the air leak on it. There is a very large leak in between the crankshaft and bearings it was losing air faster than I could blow into the engine, which to my knowledge is unsealable. So I'm gonna gut it for the few useful parts for my other engine that is working which is the same model and junk the rest.

I forgot to add
Thanks everyone for the help
