First off thanks for all of the great info I have found on this site already.. My problem is that I have a bear tracker 250 that sat in a barn for nearly 2 years and is now nearly impossible to turn over. If I pull the plug the motor turns over fine but if I put the plug back in the pull rope or electric start struggle to get the motor past tdc. What I have done so far is check the valve clearance and timing and they are fine. I am just at a loss and would love too bounce some ideas off of other members. Thanks
