MB with a Briggs or Tecumseh engine

I would like to see some MB with a Briggs or Tecumseh engine. Here in Kansas you can have a 130cc or 3.5hp engine in your bike. I would like to see some setups of a chain driven engine with the engine in the V of the bike.
Thanks!

Here's a mock up of what I'm trying to do. 26" frame, Briggs or Tecumseh 3hp or 3.5hp engine, moped front and rear wheels.

That's way more than I know how to do. Wish I could help but I can't

I might have to go with the 2 cycle engine just to make it easier.

The big challenge is the 5 inch clearance between the peddles. They can be widened. Then starting. A clutch has to be considered. All about the compromises. Keeps me awake at night, lol

What size go cart clutch would you use with a 17" moped rear wheel?

your gonna have a few issues mounting chain driven with a 3.5hp briggs from the v

I think...

balance, sence you have to line up the rear sprocket and the clutch n(or else your goin to the hospital trust me. you gotta remeber how wide that engine is and that you will need a clutch gaurd) on a diffrent note, my dad has a decent casting of a gocart cluch

on his calf...

minibike we buiilt with qa 3.5 when i was a kid. we built it we didnt put a clutch gaurd on it and he specificly said to me.
"dont put your leg over this clutch it will rip it up good, now heres how you ride it."

30 seconds later i was pulling the bikeoff him and laughing my ass off at him. he woulda popped em a good one if he coulda caught me.

LOL! Either put on a chain guard or think of something else. I see other 4cycle engines, are they narrower or something different altogether?

well yeah there are some thinnner four cycles, but if you wanna use a briggs and straton why not mount it above the rear tire and still chain drive it. safer. and you dont have to worrie about obscuring your peddles

It's all fun and games untill some one puts a thigh out. (Kidding, you cracked me up SpikedFox) Has to be a; Y'all watch this joke in there some where. And good job on out running. I am normally laughing to hard and catch the hits.
