I have a weedeater lawn tractor age unknown but 5-8 years guessing with a 12.5 briggs engine, went to start it last week and clicking was all I got so tried to manually turn crankshaft and it was froze, this week I got to tinkering with it and was able to turn shaft and it fired up like always, after it sit a bit it was froze up again, I have pulled the covering off and made sure starter was not at fault and it was not, flywheel turns hard or not at all one way, sounds like something grinding under flywheel, is there something under flywheel that could be causing this, also after getting it started I mowed yard with no problem, now its back to jammed any advice on what it might be?

Over head valve or side valve? (flat head)

Have you kept a check on the oil, etc. (just in case kind of thing) the flywheel should turn relatively easy till it hits the compression stroke... which sounds like what its doing. There shouldn't be anything other then the stator (provides power) under the flywheel, which is set in permanently. OH, one thing, make sure the ignition coil hasn't come loose and is rubbing the flywheel!!

Flat I do believe, Make:BRIGGS
Model:289707 Type:0179-01 Code:9704117A
HP: 12.5 I/C and no it does not turn easily the proper way it jams and won't turn any farther with plug out, after reading some other posts getting me think it might be a rod bolt has loosened and jamming on case, oil is always checked before use, coil is also all right and not touching, what ever it is I am going to have to rear it down till I find it, any clues as to removing flywheel bolt w/o damaging anything? I have replaced tractor with new one but want to know what went wrong, thank you for responding

Either use a puller, or undo the nut (putting a little rope down the cylinder to lock the engine will do) and pop up from underneath while turning it (but not recommended for plastic or aluminum ring gears) or undoing the nut a couple threads, hit the nut while pulling up on the flywheel.

Bangor, sounds like the compression release on the cam is bad.

honeyandbee4, you said it was a tecumseh, did you mean, "Chief Throwmmm Rod"?? Just a little shop humor, as you can guess I am not to fond, not fond at all of the tecumseh brand. Sounds like you have carb. Problems. Clean carb. Fuel line, and tank, replace the fuel filter, reassemble, and adjust carb.

Well my solution was to get a 17 hp b&s off eBay was almost new works great and cost me 200.00 of course that's cheating for a solution but it worked.. lol

[MOWERMAN2468]

Good choice. To do the work for the compression release, you still would have to pull the engine, and then open it up. This way at least you just removed one engine and replaced another. Good job.
