Pull Start Pull start won't pull when on engine...

    But it does pull & recoil when I take it off. When it's on, tho... it doesn't budge. I dunno if I'm supposed to do something special when putting the pull start on, but this plastic ratchety type thing is there, and it's confusing the heck outta me.

    I took a working pull start off my first Chinese Tanaka knock-off, and when I re-assembled it... it didn't work either. So I'm definitely doing something wrong.

    Any advice?

    The plastic ratchet is designed to engage the recoil starter then be pulled out of engagement by centrifugal force when the engine starts. Without looking at it, I don't know what's wrong, never had that occur before.

    Well... this sucks.

    I'm messing around with the old one... take the pull start off, and it pulls and recoils. Then, I take the spark plug out and try to spin the assembly thing that the pull start is supposed to turn, and it doesn't budge.

    The engine was running fine yesterday, besides the mount part of the block just snapping off. So, I don't understand why that engine would have locked up... much less the newer 2-stroke that I haven't ever used before. It's gotta be something to do with my installation, but I can't figure it out. I match the bolts up, and it should do the rest, right?

    You used bolts that are too long and locked the flywheel
    you just lost your marbles

    You should be able to turn the fitting that the recoil meshs with by hand

    Do you have the clutch lever pulled in (disengaged)?

    There is no clutch lever with a centrifigal clutch........

    What bolts, where?? And no, I still have the same amount of marbles I had yesterday.

    And yes, it's a centrifugal clutch... no lever necessary.

    That's *my* motto! However, I wanted to loctite all the bolts/screws on this new engine, because I never did that on the first one and regret it terribly. I took all the screws out for the pull start, but I didn't even remove it... just the screws, put loctite on the threads and put 'em back. Once everything was back together, it just didn't work. I tried examining the older engine first, but that was no help.

    Can you turn the fitting that the recoil meshes with by hand???
    If you can't there is nothing wrong with your recoil starter

    The motor is locked
    The bolts that go in the other side of the motor around the flywheel
    You said one of your mounts was broken.....maybe the bolt is going in
    too far and contacting the flywheel
    or you have 2 different lengths and put them in the wrong hole
    you lost your marbles.......

    BINGO!! You were right, it was the bolts. I've been using the same size bolts to hook the gearbox up to this engine for quite awhile now. But now when I take them apart and put 'em back together... they go in 1/8" too far.

    For a second there, I really thought both motors locked up at the same time. Still don't understand how the bolts worked before, tho.

    Anyway.... thanks for the common sense!
