2THPIC, It sure sounds like you are to rich to keep the glow plug hot. Do not adjust the LSN. The LSN is the last adjustmnets you make when all the brake in and high speed tuning is done. With fuel spitting out the exhaust you are to rich. Turn the HSN clockwise 1/4 turn and restart. The roto starter system on HPI vehicles is noisy. If you are conserned about the noise. Remove the glow plug and turn the engine over slowly by hand using the flywheel. Rock the flywheel back and forth in different locations. If you feel any binding or hear any clicking you should take the engine apart an inspect it. Do this with the glow plug out. You do not want to be fighting compresson. Put the glow plug back in and trun the engine over the same way. If the glow plug is hitting the piston you will feel it. I hope I was able to help.
