The first 2 things I would check is that the ring gear on the flywheel is in good shape and not all burred up. Next I would check carefully the alignment and engagement of the starter. It may need to be shimmed in or out a little. It might be binding up and not allowing the starter to fully retract once it is started.
walt, the old one was clearly not nylon, however i left it with the starter guy to order me a new one and we both decided i did not need it back. the pinion is nylon. i have no idea what the flywheel is made of, how do i tell? are you certain that the 16 tooth gear is correct. i have also seen some 14 teeth gears?
while i am getting attention , the engine runs great for a while and after about 20 minutes it starts to bog down and then i have to choke it to stay running and then after that the engine starts to fade quickly and eventually quits. let it rest for 30 minutes and same thing. before i spend 160 on a new carb is there a good carb cleaner?
can anyone tell me what the flywheel is made of on the 16 hp briggs that came on the 7016H ? how many teeth are supposed to be on the starter bendix? the starter has gone through 3 nylon pinions. the flywheel appears to be in good shape and the starter is on straight.
