Think I just bought me an 1811

Guessing this isn't a ring job anymore? Just trying to figure out my long term plans :-/ what do you think it would take to restore this engine to good running condition?

Edit: Guessing it's not going to help the situation if I put the thrower on it and blow baby blow?

Not sure the blower will hurt it. Just keep a close eye on the oil. If you have something else you can use that is in better condition I would do that but if the 1811 is it well Ya Gotta Do What Ya Gotta Do. I would try to rebuild it depending on what it needs and what it will cost or re-power it. If you can find a 2185 that runs good and is cheap they make good organ donors.

I'm with Sam.

You may not have to go deep. Jugs, pistons, and rings. It won't be long and I can tell you if it's affordable. I have at least 2 KT's sitting in the shop waiting their turn.

Don't forget the Gov gear that seems to be prone to failure. Last Mag 18 I had, had a window in the block from that plastic gear going south.

Just for my own edification, what do you think has happened to this motor with seemingly "only" 79x hours? I know it's just "worn out" but in this case, what does that mean? Cylinders gotten worn and rings not sealing allowing an inadequate seal/compression? Valves not seating right? I know there's not "easy" fix, I'm just curious what went wrong with this machine

If it's got close to 800 hours on it considering it's age and guessing it didn't get the best of care that's about right for needing a rebuild. If it was one of those engines that was started and shut down often, (the start it mow for 30 minutes and shut it off) you have to consider the wear that takes place every time it goes from cold to hot. The pistons expand faster than the jugs as it goes through a heat cycle causing accelerated wear. If it ran 8 hours a day will get maintenance my guess is it could go 3000 or more hours.

I have a CH18/20 just waiting in the wings to be placed on my Super....

Thing is, my M18 with 920hrs runs like a beast....I just had to replace the front seal a couple of months ago but I had it out and milled the heads, new gaskets and both front and rear seals to include oil breather gaskets....

Cranks right up and purrs like a kitten...

But the day I would sell that CH would be the day I throw a rod in the M18!!!

I would take that Mag and run it till it drops....!

How bad does it smoke and did you do a leak down test on it? Those testers are pretty cheap (less then $40) and will point you in the right direction.

I hate to do that to an engine, I'd love to save this one but if it happens it happens. I'm actively keeping an eye out for a 2185 or similar for a repower. Love the tractor just need a better engine in it.

No I did not do a leak down test on it and smoking isn't horrid, though its worse than I'd like. Quick acceleration in throttle? Puff of smoke. Run hard off the governor? Puff of smoke. I've even seen a super slight hint of smoke idling after running hard for hours.

Just keep the oil full and add some MMO, just run it and don't worry about it
