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.
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.
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.![]()
