recoil stater blowing up!!!

[cartman308]

Please help me!! My recoild starter on my Briggs 11Hp IC engine is literaly blowing up! I dont mean the spring is unwinding. I mean the pulley and pawls are breaking!

This has happened twice. First time, I replaced the spring, pull rope, and pulley. This engine is in a Swisher trail mower. I thought the belt may be to tight so I took the belt loose. Engine started once. Stopped and tried again. Poof. Blew up.

This time I replaced the pulley, pawls, and pawl plate. Reinstalled. This time just pulled slowly to turn engine over. Second "pull" the assembly broke again!!!!!

When it breaks the posts on the pulley that keeps the pawls from over extending break. And the posts the pawls set on snap off. Rendering the pulley complete junk.

What on earth is going on!!!!! Help me!!!!! I'm over 100 bucks into this and I can tput anymore in it unless I know its going to work!

B&S "customer services" was absolutly no help............

Well, one question is...Can you show the wrappers of the parts that you have put on???? If they are not real Briggs parts, they are worthless junk.

The other one is, does the rope rip out of your hand? If so, you may have a dinged up flywheel key....

Parts are genuine Briggs bought at a briggs dealer/service center. At least thats what the packages say...........

With the new belt it was a bit hard to pull but the second time it broke when I was just pulling the rope out. Not trying to start it and belt was not on pulleys.

I got the long end of a ratchet strap and rigged up a pull rope. It works but is as dangerous as a cocked cannon. Lol. I had to do something. Its been down two weeks and the grass at the pond was getting out of control!

If the starter pulley housing is bent and not aligning correctly with the starter cup, or is not centered on the starter cup, it will cause the pawls to overextend, and get spit out. If the engine is kicking back it can break the pawls also.

the susa starter system is a weak system.

I was thinking alignment as well but there is really no way to adjust it.

Saying this setup is weak is an understatment.

Is there somewhere I could cross referance bolt paterns? Before I sink anymore money into the starter I'll just try to find a new engine.

Check the flywheel key first!!!!

Check the flywheel key first!!!!

Will do! Thanks for the heads up!

What is the procedure to check the flywheel key? Looked at the diagrams and cant get a good game plan.

While the starter/blower housing is off, remove the nut inside the starter cup, remove the starter cup, and you should be able to see the flywheel key sitting in its slot in the flywheel, make sure it isn't offset, or broke in two.
