Another no start problem!

[RenegadeStang]

Let me add to the list.
'98 Yard Machine with the Tecumseh 12.5HP. Was previously having trouble starting. Pulled the starter apart to find the magnets in pieces. Replaced the starter as well as the solenoid while I was in there. Changed the oil, too! :biggrin: Turned the key, the engine makes 1/4 to 1/2 of a revolution and then it locks up, with the starter being stuck in the engaged position. I loosened the starter to allow it to return to the disengaged position. Turned the flywheel of the engine by hand, so the engine isn't seized up. Retightened the starter and tried again, same results. Anyone have any ideas?

Just to be sure, is that battery full charged?

 

[RenegadeStang]

Yes, battery is fully charged and has the proper number of CCA's.

Read another thread concerning a B&S engine with the same symptoms. Someone commented trying to turn it over with the spark plug removed. Can I try this with my Tecumseh as well?

Pull the spark plug out and try turning it over. Post back results and engine numbers.

 

[RenegadeStang]

Pulled the plug and attempted to start, same results. Even jumped it off of our Camry just to be sure.
Engine is Tecumseh OHV125 206604B.

Are you saying that with no plug in the engine the starter would not spin it over?????

That is correct. I'll get maybe 1/4 turn on the flywheel then it locks down. Yet, when the starter is disengaged from the flywheel I can turn the flywheel by hand. Doesn't make since to me.:confused2:

I know that this manual does not have your exact engine in it, but I think it will be of some help to you. Go to this website and download it.

With that said I would be pulling the starter and either bench testing and rebuilding or replacing it.
