Tecumseh hh60 lost timing after flywheel removal?

[Mountain_anderson]

Hi all
I have a Tecumseh hh60 with the internal coil on a Troy bilt horse. It would start and idle fine but lose power when put under load, just putting it into gear it, would move about 6inches and would cut the engine. I noticed it had a bad spark so I replaced the plug. Tested it and the plug still had the weak spark, removed engine face, gas tank, and fly wheel to potentially clean the points. Cleaned them and set them to the proper gap. I reassembled and now it won’t start at all, plus it’s hard to pull. No start, hard cranking, and no spark as well. Not sure if I did somethinf to affect the timing? How could I fix this?

Since it has no spark the first thing I'd suspect is that there's reside from your cleaning job left on the point faces so they are not making good electrical contact. With them "open" give them a shot of electrical contact cleaner, allow to air-dry, then repeat. Be sure all the cleaner has evaporated before trying to start the engine or turning it over to the point the points close.

While you're checking that you can verify if the flywheel key could have slipped out of place when you were putting the flywheel back on.

IF it was "out of place" enough to get pinched the flywheel could be wobbling and grinding against the coil laminations, make it hard to crank, and affecting spark, as well.

Also make sure that any remote kill wire , if so equipped , is not grounded where it shouldn't be.

But why is the engine tight? Can you hear anything rubbing? Take the shroud back off and see if the engine turns free... make there's no bolt rubbing on the flywheel.... like the two on the bottom that will rub if too long a bolt is used.

Some of those 'H' motors had the magnets glued to the inside of the flywheel.... if you hammered on it to get the flywheel off, you may have fractured that glue joint and now the magnets are stuck to the magneto , and jamming up the works.
