What causes difficult pull starting?


The magneto/coil may be rubbing the flywheel. Also, there could be a hydraulic lock with fuel in the cylinder. If the engine doesn't have a clutch, whatever is down the line from the engine may be sticking and making pull starting difficult. Thee could also be an issue with the recoil starter, causing the rope, spring mechanism or starter pulley to jam.
