****, If your getting that pissed over a pullstart, Might as well sink that boat now ;D ;D ;D
You might want to LOOSEN Your glow plug some, and let it fire and tighten it up. I have seen where the engine locks up as your pulling it, that could get rid of some of the stress on the rope. I have used paraichoote rope on one of mine and has worked great.
and if you come on this board pissed at your boat problems, and ask for help and snap at others here, that will not get you to far. we are all a great group of guys in this hobby/board and there is plenty of help, and plenty of wise cracks here. but its all fun and games, and if you ask me, there is no better board for info and help.
