My Tec sounds like it's trying to hack up a hairball.

I just picked a used Husqvarna 1130STE topped with a Tecumseh from a relative knowing it needs repairs.

Engine details:

Tecumseh 11 hp
Model: OHSK110
Spec: 221731D
DOM: 2003

Here is what I have found:

The pull start is stuck. I can pull it about 2 inches and it stops. If I jiggle the line, it'll come out a few more inches but, won't go any further. It locks up tight. This means that there is no chance of using the pull start to fire it up.

Since the pull start is out of service, I plugged it in to use the electric start. Well, that didn't go so well. The engine did not try to turn over but, I got a high pitched grinding noise. It sounds almost the same as when you turn the ignition on a car that's already running.

I'm a believer in not helping those who don't help themselves first so, here's my thought. The electric starter was used to the point of failure, some of the teeth got torn up, fouled/broken fly wheel, and that also fouled the pull start.

Thoughts?

That's entirely possible.

I have an OHSK100, for reference, the pull starter doesn't touch the flywheel teeth. Now, if they broke and went "spraying out" and got into the pull starter area, they could cause a problem. But you could slice all the teeth off the flywheel, and the pull starter should be unaffected.

Do you know if the engine can actually turn over by hand? I'd start with removing the pull starter & shroud. It will give you a chance to see if the pull starter is visibly jammed. And more importantly, it will let you try turning the engine by hand, to see if it still gets stuck. Remove the spark plug if needed to make it easier to turn by hand.

You may have to take more shrouds off to get a better look at the flywheel & starter.

Hopefully this is just something jammed into the starters, and not a broken rod that has locked the engine up, or something like that.

I agree that you should remove the plug, and recoil mechanism, and see if the engine can be turned over.

Stick a NEW LONG pencil down the plug hole to see if the piston is moving, (not that two inch one you have been using for the last 2 years and should have replaced by now). Also, remove the valve cover and see if the valves are moving.

If the engine goes round and the piston goes up and down, and take a peek at the ring gear teeth on the flywheel. If there is damage on the ring gear, then you have a dilemma. To re-power or fix, that is the question. Cost of parts for an older engine vs cost of a new engine would probably be a factor.

Work fascinates me.

Yes, the oil level is good.

Sounds like it is trying to cough up a hair ball. How could that be if you can't get it to turn over?

The starter bendex may not be fully engaged. Maybe a little lube might work on that. The rest will reveal when you get the shroud [s] off.

Inspection. Remove the pull cord assembly and see if it's jammed or if it's the engine.
Remove the starter and inspect the flywheel gear and the starters gear.

See if once the pull start and electric start are removed the engine can be turned by hand, spark plug removed.

Make sure the windows are up before the snow plow goes by !!

I took off the pull start assembly. For that, the line was fouled but, I got it straightened out. I pulled the plug and turned the crank, the piston is not moving. I'm hoping it's only the connecting rod and it did tear up the block to bad. my neighbor and I are going to dismount the engine and tear it apart to see if it can be repaired. If the block, is to torn up, I'll just replace the engine. I'll probably replace it with a 414cc LCT engine.
