So I recently acquired a mower from a neighbour who over torqued the carb bolt into the head and sheared the bolt off inside the head. He tried to drill it out and damaged the side of the housing, I found what looks to be a similar engine with the same model number. However it’s been removed from a leaking power washer but runs well. What problems might I run into doing this?

None if it is a GVC engine and not a GX? engine .

My mower is the red and the donor is black

any help is appreciated. Thanks in advance

There is no throttle on either?
If one does and one doesn't, there might be an issue there.

I have the carb and throttle for the red one. It’s removed because it broke off. Black one is just the motor

I do have the carb. I’m thinking that’s what you mean by throttle?

A lever on the handle which, when moved, causes the motor to increase and decrease rpm's.
Some mowers don't have throttles, so if neither do, great!
I believe both should have carburetors.

I do have the safety and the drive lever but not a separate throttle. Sorry for the misinterpretation.
Reasoning for my question is there are a few for sale and all look similar. However one ad on a separate mower says ‘customer returned as they bought the wrong mower...short crankshaft’
Ive done a Troy built powered Honda gcv160 and swapped out a motor with an engine from another. Donor came off another mower and worked no problem.
I just haven’t used a power washer motor and was wondering if there was any truth or concern with this crank shaft length
Again thanks for your knowledge. I’m learning as I go and have searched but can’t seem to find the answer I’m liking for

Being it is kinda hosed and have nothing to loose, i would take my dremel and cut a slot on it and try removing it with a screwdriver. It should turn pretty easy.
-OR-
If u can find the hw, weld a nail to the screw and remove it.

Unfortunately power tools. Sockets wrenches all that sort of thing I have. Dremmel style tool I do not.

My understanding is that PW engines have a heavier flywheel in order to compensate for the fact that there is no blade on a PW.

What are you trying to do? Are you thinking about swapping engines or using parts from one to fix the other?? Either way, it won't work. The lawnmower engine is a metric crank and a specific length for that application. The pressure washer engine does not have a flywheel brake (safety first!) and has a SAE crankshaft. You will most likely encounter more problems than it's worth. Too bad he buggered that up like that, but the gasket surface is still good. Someone that actually knows how to remove broken studs should be able to remedy that issue.

Thanks guys that’s what I wanted to confirm. So I won’t buy that engine. I guess I have to remove the engine and take to a machine shop to have the bolt removed? May cost more than it’s worth, I could just sit on it and wait for a motor

let the swap begin

Almost done guys. Only issue is the 4 bolts that mount into the deck. The replacement motor didn’t come with them. My original motor now removed has bolts but they are much narrower and drop into the thread of the donor engine. Any thoughts
