best lawn mower cart image
Ben
So i am trying to build a go cart but am not sure what to use for the engine. i have a lawn mower and a chain saw, and i might have some other machinery that have engines. any ideas? i have maybe 200 bucks to throw around for this project
ps. i dont know much about engines and all
Answer
First things first. You cannot use a vertical drive shaft engine in a horizontal application unless you use a transmission. In your case, that would kill the budget. Basically, the lawn mower engine is out of the question.
Next, the chain saw engine will not have enough power to push a go kart. It would suffice on a scooter, however.
Here is what you will need to round up to make this work.
1) Find an old tiller with a fairly good size, horizontal shaft engine. Most of them come with this already so it wont be too hard. Five horsepower will be plenty to get you going.
2) Buy a clutch, sprocket and chain for your drive assembly. The clutch mounts to the engine drive shaft and works off of centripetal force. The sprocket mounts to one of your rear tires and the chain connects the clutch and sprocket together.
You now have the possibility of a running go kart for less than two hundred.

Does a typical push lawn mower have a vertical or horizontal crankshaft? Could it be used on a go-cart?
Questioner
Also, if you know, how fast would a 5HP lawn mower engine move a go-cart?
I realize now that it has a vertical crankshaft. Would a snowblower engine 5-6 HP work better? If it does, why does the engine move the snowblower wheels very slow?....Would i also move the axel that slow?

Answer
If it is a typical law mower it has a vertical shaft and would be too much trouble to rig as a go cart motor, but it can be done. Just a lot of work to do it. Typical 5 hp brigs can run as much as 50mph or more, but it won't last long turning those rpm's. You would be better off just buying a Rupp engine with about 8 to 10 hp. Lot better engine than a briggs for a go cart.
