Carter bros mini monster

So how many of us remember this? I picked this up a few years ago and I think I’m going to finally start working on it. I saw this in a go kart shop when I was a kid (Fastrak go karts). And I fell in love and told myself I had to get one in the future. The chance came and drove 2 hrs away and got it.
5hp flathead with electric start, dual band brakes. The guy that had it “monkeyed” with it so it’s not 100% original. No big deal. Not looking for that. I’m debating on either fixing up this Briggs or buying a “7hp” Duramax electric start engine and going from there. I was lucky enough to find a truck body this past week (mind the paint) and fits almost like a glove. So anyone and everyone give me your input and advice on this go kart.

If that Briggs Fun Power is not seized up, you can easily get more power out of it with a cam, and maybe a billet rod and flywheel if you really wanted to get some juice out of it. The sky is the limit on aftermarket parts for those, and they run pretty good stock. Best of all, it's already installed in the machine, everything is done.

As enticing as a new $200 engine is, it will require some work to get it installed. I would definitely keep it as stock as possible, not because it's going to be more valuable someday, but because it's the easier, and less expensive route, and will result in roughly the same machine.

Yes sir it is a Fun power engine, that’s good to know about the parts to “amp” up the motor some, I love a flathead sound but haven’t had much experience with rebuilding one, I’ve tried but more or less failed with it, you have a point though, everything is there just a couple extra bonus parts to wake it up some should fall close in the range of a new motor.
Thanks Dave

This type of kart doesn't require or even benefit from a lot of power. You could never drive it very fast, and it's geared for any hill you'd take it on. The flat head stock has plenty of power. Is there something wrong with the engine now? The only weak link is that Pulsa Jet carburetor. Sometimes the lower pick up gets clogged with varnish, and sometimes the pump gasket (that square area on the carb) fails.

I kno:( ima speed junkie. Just an awesome kart that doesn’t go fast, But no sir. Last time I started and rode it (2015) it ran ok that I remember just was slow. And from the past Briggs that I tinkered with definitely were a pain to get the carb out to clean. I did look at the hearing setup earlier this evening and it’s crazy looking compared to what I’m use to seeing, basically I bought this go kart and rode it once and it’s been sitting since then. But now that my Baja is done, on to this cool little rig :scooter::scooter::scooter:.

Pfffft, Briggs and the Pulsa-Jet carb are easy to get running; they're so simple. I just like how it has a built in fuel pump and it's always pumping when running. No need for a gravity-feed tank.

My advice is to stay away from E10 gasoline or ethanol-gas in any concentration. Bad news for carburetors. I use 100% gasoline or Avgas.

I didn't say they were difficult to get running, what I said was that if these carburetors were the weak link. And they are.
