Of course for me any diesel conversion, but those aside, my favorite is Onan, hands down.  Smooth abundant power!  Kohler & Briggs cast iron right behind Onan.

Cast iron B&S. Mostly because of better availability in my area. I'm also partial to singles over twins, because they have better fuel economy, and less parts the break.

I love the old V twin Onans, I know all the cons, but the torque and the sound through dual exhausts with the right mufflers is second to none.

My garden tractors don't have Engine in them, they have a Motor.


General Electric Motors,  and I like them. :thumbs:

You can't beat a Wisconsin 2 cylinder THD if you just want to impress folks.

I like them all.  I have several of the two cylinder Wisconsin THDs, Kohler K301, B&S 13, Even some Honda's.

In the 1970's,  the company I worked for as a small engine mechanic  closed up.  A dear friend of mine at that time asked for the B & S repair manuals, which I gave to him.  He has passed away.  I sure would like to have the old factory manuals.

LilysDad, I picked up one of those THD engines over the summer. A guy wanted to sell it to me a couple of years ago, but I didn't have a need for it. After swinging by his place to get some other parts that I needed, he mentioned the THD again. It was sitting under his bench for years and wanted it gone. He gave me a great price on it, so it came home with me.I haven't messed with it until you mentioned the THD in your post above the other day. Well there was no spark, so I cleaned the points and got great spark right away. I bypassed the fuel pump and just gravity fed the carburetor. The engine fired up after four or five pulls and runs extremely well. It has an exhaust manifold like the old Yazoo mowers, but the carburetor is backwards on my engine and I can't find another THD like that. I have no idea what this THD came off of, but it was built in 1961 according to the serial number on the tag. I'm thinking about putting it on an Economy tractor, but I would have to change out the crankshaft and drill and tap the block to mount the hogs head. I've seen a few good crankshafts that will work, so I may just go for it.

My first choice is the engine that is running. :D  I really like the twin cyl's for smoothness and easier to be around than the big cast singles.

(tie) 1. Kohler K or M series single    1a. Kohler opposed twin.

2. onan opposed twin.

3. (hate to say it) Tecumseh snow king   better if old enough to have adjustable carb.

4. Tecumseh lav series. push mower engine.  especially the XL series with older carbs.  had lots of them that I tried to kill and wouldn't die.


towards middle of pack. any briggs, up to maybe the quantum series  age wise

down the ladder, newer Briggs than that

further down Tecumseh with nonadjustable carbs.

in the sewer,  below rock bottom......... Honda AND any of their "clones" too (predator, etc)  wouldn't have even for free.

I didn't used to have a favorite but I'm becoming more of a Briggs person. 

Top of the list is anything that smells and sounds like a diesel.

All of mine have Kohlers, but I do like the sound and power of Onans.

I will most likely put the Wisconsin twin in a PK, MNGB. I know a guy with some rolling chassis, so it would make a great project.

L head briggs by a long shot.

May not have the sound or torque of an onan, but they will pull their guts out all day long and never give up. Plus they have an incrediable will to live, as in, it can sit outside in a bush for 15 yesrs, and 9 times outta 10 after cleaning the carb and cleaning the timing magnets theyll run.

Not alot of experence with the K kohlers, but i know their V twins can be finnicky, but honestly id put them right up against a comprable onan for grunt.

Onans and wisconsins? Well, maybe they are good on the rare occasion they run. For some reason i always have had issues with the few i had.

Here are three of mine.

1988 Craftsman II, 1988 JD 165 Hydro, and 1978 Roper 20T. Can't say I have a favorite, I enjoy all of them.
