I have a 1/8 scale nitro buggy and i just bought two new glow plugs. I installed one today ran it for aproximate 30 seconds to adjust low speed needle. I pinched off the fuel line it reved then quit after about 3 or 4 seconds. But it never would start back up i remove glow plug and check it for glow and there is nothing no glow at all. So i remove the brand new glow plug from another car. It runs the same and again once i kill it, it dosnt start back up. Again after removing glow plug it dosnt glow. The engine needs at least a little bit of tune but even if it ran a bit rich i cant see that causing plugs to fail thst quickly. Litterally both plugs died after less than a minute. Any ideas as to what i can do to fix this issie.
