    I have an older 48" Exmark walk behind. Being as it is older, It only has a pull start. The problem I am having is that sometimes it almost rips my hand off when starting it. It rips the handle right out of my hand. I have been told to pull the rope slowly to turn over the engine , then pull to start it. I just spent over $300 in repairs including a tune up. It just seems dangerous. Anyone know what the problem could be or what I can do to keep from getting my fingers ripped off trying to start this thing?

    Thanks,

    Dan Johnson

    check the starter clutch it could be not releasing right also valve clearance and ignition timeing could be off

    I have had the same thing happen to me. It surprises me everytime it happens. It is not just limited to exmark engines, kohler, kawisaki. I do not know what causes it but it hurts.

    sounds like the flywheel key is worn, or the timing is off, valve timing could be causing the problem as well.....

    I had a Kohler that did it, and it was miserable. Try like you were told to pull it til you get to the point of resistance, then let the recoil go back in, then pull her good. If you still have trouble, look to other problems that were mentioned above.

    It has something to do with the compression release. Mine has caught me off guard a couple of times.

    What's the deal with my 12.5 Kohler then? It is super super hard to pull, and when I do get it started it seems that everything wants to come back out of the carb instead of the muffler. I think that the exhaust valve timing is off, because the exhaust is coming out when the intake valve is open. Anyone?

    sheared flywheel key is the usual culprit.
