    How much pullrope are you using?????

    I'm not running anything radical. Billet flywheel and rod. Stock cam 212. I always rotate the engine with the pull rope until I hit the compression stroke. Then reset the pull rope back and give her a good yank. Since I've started doing this I've never had a problem.
