I'm having issues with my nitro engine. When I first purchased the engine I broke it in to the tune of 25+ tanks with the help of a heat source to bring the engine up to 200 degrees anything lower and it just would cold seize. I'm about 45+ tanks into it now and I've been running the car medium to top speed (as i assume the engine is broken in) Anyhow, the only way I've been able to start the engine is with the glow plug slightly unscrewed on the starter box. Now, going back to about 2 weeks ago I was able to do this without any problems. Well I thought so, I tried it again the other day and for some reason the engine is just seizing at TDC at the pinch point as to where I burned up my brandnew starter box engine trying to turn it over. The question is what am I doing wrong?
