I'm running the Losi Mach427 and I think it's dying. I know the compression is low. I can stick a finger in and turn the flywheel without to much effort. But, when it's running it runs very good and strong and it holds a tune. the problem I'm having is it keeps blowing out glow plugs. The first one looked burnt and distorted so I richened the top and bottom. The next two in about a tank each are broke in the coil a little way down. They don't look wet but not burnt either. It's plenty rich (or so it seems)and has a strong smoke trail. I'm wondering if an engine that's going out will do that? Or any other ideas you might have.
