    Valve clearance specification is .004-.006 in.  Do I adjust to the low, middle or high end of that?

    Attemping my first valve adjustment. I am assuming that the compression release, on my John Deere snowblower with 342cc Briggs and Stratton single ohv engine with approximately 25 hrs. run time, is not working.  I have almost pulled my arm off pull starting it. Electric starter can't turn it.  It came this way right from Lowe's. I did not realize it wasn't suppose to be this hard to pull.  Live and learn. Runs great once started.  It's still under warranty but from what I've read online I think this adj. will fix it and it seems easier than hauling it to the shop. Thanks for the information.

    I will say up front that I don't know anything about 'snow blowers'!
    I would suggest though that if this machine is still in it's warranty period, take it back to the dealer and get them to fix it. If you start playing around with it you may void your warranty!
    Another suggestion is to read over the 'instruction' book.
    Remember the old adage 'When all else fails read the instruction book' lol
    It sounds to me like you may be trying to start the motor 'under load' and you may not have disengaged a 'clutch' of some description!
    Good luck with your  quest!
