Is there anyone who still makes a go-kart flathead, like the B&S flathead or is everyone making OHVs now?

Briggs is still making the 3.5hp Flatty. They have had to completely reconvert it to a bowl carb with an updraft manifold and top mounted tank.

Lifan/Clones are still making a 2.8hp motor that they use on DoodleBugs, ag sprayer pumps, etc..

That's all i can think of that's left.

Hmm well that sucks. I was hoping to find someone who was at least still making a 5hp flatty. I'd like a flatty mainly because they're easier to work on than the OHVs.

Thanks anyways! :)

If you say so... but that's another whole argument that time and technology has completely proven wrong.

Briggs still makes the Quantum flathead that is similar to the old 5hp 13 series, but only in vertical shaft format. I have converted a couple to horizontal, just had some technical difficulties with stripped threads and a leaking homemade manifold.

Is it really necessary to start a debate? If you don't like them, fine. Some people just like the older design, and might be more familiar with it. I think they are more fun to work on IMO.

I actually am more familiar with a flatty, mainly because when my brother was racing karts (back in the 90s) that what he ran. I helped him work on his motors, so that's what I know.

NCKarter, Does it have to be a brand new engine? Lots of 4-stroke kart racers are currently switching over to racing the clone classes and selling off their blueprinted flattys pretty darn cheap nowadays. Around here I've seen quite a few running/race prepped flatty's (w/spare parts) with asking prices in the $100-$200 range. A lot of these engines originally cost between $500 to $1000 to have built.

No, it doesn't have to be brand new. I'll check out the local kart shops. Thanks for the advice. :)

Yeah try that but you'd probably get a much lower price dealing with a racer instead of a kart shop. If you have a kart track I'd go out in the pits and ask the racers if they know of any for sale and/or check the tracks classified section if they have a web site.

Another really good way to get deals is to post your own Wanted ads on craigslist. At the bottom of your ad be sure to include the different spellings commonly mis-used for Go Kart (Gokart - Go Cart - Gocart) so anyone preforming a search will find your ad. You should also search your craigslist using all these different spellings to find any ads you might have missed.

Word of warning though... be CAREFUL on ebay looking for flattys. Many guys are putting theirs on there because they have bought clones and don't feel like freshening them up. So they use "high performance" "racing blueprinted" and stuff like that to make you think these are fast fresh motors when they are really actually tired.

And there is another guy on there that takes bone stock 5hp motors and paints the tins and sells them as race motors.
