Ok, my friend got a RC10GT and when we first got it the glowplug was bad so we changed it and cranked it right up and we took it home and then it took a little while to get it started and we finally did and then it ran without the glow starter and then it would start dying when we took the glow starter out. Then today we tried it and it took forever to get it started and we finally did and as soon as I took the glow starter out it died. Then we tried to start it and it would start for a second and then die instantly and then it fouled the plug. Can anyone tell me what is wrong with it?

um did u brake it in the motor??

We fixed it. His mom has a friend who has been doing it for 8years and he came over and helped us get it fixed. He broke it in and is loving it now.
