When attempting to pull start this motor the mag plat / armature plate where the throttle cam is mounted to travels past the cam follower on the carburetor...this causes the carb follower to cut stuck on the back side of the throttle cam. Motor has not ran yet, it acts like its going to for a few seconds but then dies. The problem described doesn't occur with each pull, but can be repeated every time when a vigorous attempt is made to pull start it Motor model is 25R74M
