M18 engine head milling
 

Last month, bought a 4.5 acre house/property. I was going to buy a zero turn, but in the barn was the previous owners 1811 that's been at the property since it was new. After using it a bunch, I'm saying F a zero turn, because I love this mower. It's nostalgic, the hydro system makes for an efficient and effortless mow. Plus, has a 50" deck. Had to put an ignition coil on but it's a solid runner now.

Is there a norm for head milling to run on 93? Carb jets to match?

Valve adjustment specs?

Is there an engine code I could search other than m18?

Anything else I should know?

Why run on 93? Just use 87 and it will be fine.

You say that now. ��

Ditto.....no point in running 93 Octane.

The 1811 rolled out of the Factory with a Kohler M18-24506 Engine in it.

Welcome
 

Another 1811, great! What kind of shape is it in? Snap a bunch of pics and post them here for us.

I just got an abandoned 1811 last year and I've been going through it to fix the neglected items. I'm impressed with the quality. I posted a lot of pics of my repairs that might interest you.

I bought a dozer blade and a snow thrower for it too.

I'm near Annapolis MD. How far away are you?

Higher octane is for engines with high compression, it basically keeps the fuel from igniting early in high compression engines so there no need for it in a garden tractor engine.

You don't need 93 octane. Where on earth did you get that idea?

I love Cub Cadet tractors..... but I'd rather mow with a ZTR. Way more efficient. Especially if I had 4.5 acres to cut, which is a ridiculous amount. I'd keep the 1811 for chore work. Get some other attachments for it....but I would get a ZTR. Or maybe in your case a 12' batwing finish mower, lol.:biggrin2:

Didn't Sam have a setup for sale??

Who said anything about needing 93 now? Lol. Did anyone read my post or was I not clear (I dunno how I could have been clearer)? I'm wondering if there is a "run of the mill" milling (pun intended) amount that will increase compression to run safely on 93 octane.

Otherwise thank you for the info.

Mower is in good shape, have all kinds off attachments as well. Obviously the old man original owner loved it. I think it's perfect for my yard, half the property is woods, other half grass. It's also a mix of flat, hills, and....rocks. a zero turn wouldn't really save me a lot of time

You can run it on 93 the way it is, no milling required. You don't have to have high compression to run 93.

Why do you feel the need to run 93?
