As far as mass produced I would have to guess Kohler followed by maybe Wisconsin. I assume you mean largest as far as most advertised HP. The Wisconsin probably out weighs the Kohlers ie: better boat anchor.

well it kida goes hand in hand as far as horse power but I was mainly refering to physical size im working on a project that requires a large looking engine and I prefer it was a flathead

 

[ATKRIDER]

A Kohler K341 is about 17" tall and like 12" square where as the Wisconsin is 19" tall and just a fuzz narrower. Wisconsin model is AENL. I just happen to be looking at them both if you want exact dimensions.

 

[metal man]

the biggest i can think of a e4 Wisconsin 4 cylinder , the next a e2? Wisconsin 2 cylinder .
well at least in motors you could lift that is , seem some huge one lung hit and miss air cooled motors

the largest flathead motor past or present.

Briggs made the biggest they made many 17hp single cylinder and for 1 year a 20 hp single cylinder if you are gonna restore or get a motor for a mini bike use Briggs there strong good engines with so much power you can spin rims inside tires.

Yeah, I saw a video on youtube of a Wisconsin Air Cooled V-4 engine.
It was rebuild and made 65hp (V465). Sounds Awesome !!!!

Anyone got pictures of these single cylinder giants or a link to some pictures?

You should be able to find them.. There were millions of them made.. Look around antique tractor websites.. Economy used the 14 horse Wisconsin single cylinder engines.. Those things are massive..

I have a big ole flathead motor, it has a 1 1/8" diameter output shaft and an external magneto. I haven't messed with it since the guy gave it to me. As a matter of fact, I haven't even moved it, its heavy it should have come with a hernia belt! I'll get a picture next time I get out there.

as far as 1 cyl flat head the biggest I have seen is this thing sitting in my back yard

The Wisconsins use an external Mag..

Jesse,
You need to get that shed done! Nice motors you have there.

 

[KB2ROCKET]

In what era and HP range?

The Lister L as I recall was a bit bigger than 4 inch in bore ( but very long stroke ) and I think they tipped the scales around 700 pounds....

YouTube - Starting Lister L after 40 years.

Sure you can say YA but thats like stone age stuff...
In one form or other the L or basic design derivitives remained in production untill 1982 with the last of the CS-8 coming off the line in Dursely for deomestic markets...

That much said much shorter stroke higher speed flate heads were available few make the kind of shaft snapping torque of the early letter motors from RA Lister and Son.

I'd love to see the mini you cram that beasty in.

Lister auto truck or rail truck?

I am an electric and diesel qualified narrow gauge motorman lol. IIf I were a rich man I would ride my little train around my house take my autotruck to the store, and use a mini to get from train to truck lol...

Wow this stuff is big let me share this idea with you find a large engine like a Wisconsin then fab a old school minibike frame for it using larger diameter tubing in other words scale everything on it up to be in proportion including the seat and tires then when an adult sits in it whamo!! He looks like he's 13 years old again
