I recently purchased the 2.5R to go into my Nitro Stampede. After following all break-in procedures, the engine ran great. After about a half of gallon of gas (after break-in) I hit a tree around half throttle. There was little damage, The exhaust popped off where it is zip-tied, an easy fix, and the engine was still running. I brought it to me, shut it off and fixed the exhaust. The engine wouldn't start, so I replaced the glowplug, although it still wouldn't work. I can't figure out why. Around TDC, the engine feels very tight(as if it was flooded, although it isn't.) When I remove the glow plug, it spins fine, no hang up at the top. I feel like I am overlooking something.
Thanks in advanced

After about that much fuel, the engine will need to be leaned out a bit. Break in settings are usually rich and the engine may not run well after it loosens up until you lean it out a bit.
