Maybe this will help some people that are trying to build a go cart with a vertical shaft engine.

You'll probably (depending on the type of clutch) have to mount the clutch on a jackshaft.

That sounds good, tho I woud advise against using a fixed rear axle without a diffrential. Your turning will really suffer.

That's what i'm going to use for my go-kart. I just finished fixing up my 3hp engine, it seems to be pretty good, I don't care if my kart dosen't go that fast, i'm just going to drive it arround my street anyway since I don't want trouble with the police or anything.
Basically It's going to be:
Motor --> Twisted V-belt --> Clutch ---> wheels axle.. Would that work? Or do i need to have another pully between the clutch and the twisted V-Belt?
Thanks
Andy.

well you can take the differental and rotate it up so that it will accomodate a vertical shaft

why dont you find a four wheeler or golf cart rear differental. If you want to know what it looks like look under the back of any rear-wheel drive vehicle. However instead of using it horizontally turn it vertically. You might have to make some new mounts to attach it to the frame, but this would include berings and all.
I would try looking at motorcycle shops (usually they sell 4 wheelers as well) also try small motor repair shops

Ok i will consider the first option because the second is to complicated. I will tell u the result after i find a really long belt. Anyway Thanks alot for youre help

You need to use a very long belt to do this. At least 3 feet between the engine and the other pully. Otherwise the belt will twist itself off...If you look at old machine shops (from the early 1900s) they have many belts like this as they used to have one monster steam engine powering the whole shop, and then a system of belts and clutches to transfer power. Their twisted belts were often 15-25 feet long!
As for converting a vertrical engine to horizontal, yes, it can be done. The problem is that you need a doner horizontal engine, or at least a lot of parts from it...I will assume a standard Briggs and Stratton lawnmower engine here. This is what will have to be changed:
1. The oil splasher on the cam will have to be removed, and the dipper from a horizonal engine installed on the end of the connecting rod. This means opening up the crankcase. At the same time, you might as well replace the seal at the crank.
2. The carb and fuel tank will have to be changed. Best bet is to grab a float type carb and run an external fuel tank. You need to mount the carb so the orientation stays the same. Using an external fuel tank eliminates the need to custom mount the existing fuel tank.
3. Stock aluminium flywheel should be replaced with a cast iron unit. This insures the engine will have enough momentum to maintain an idle when it is running no-load (ie. clutch disengaged)
4. Have fun mounting. My first thought is a big 90 degree metal L bracket bolted to the existing mounting holes. Make this out of steel at least 6MM thick.
5. The oil fill hole will have to be modified, and the drain is no longer functional. Easiest way to deal with this would be to install a T fitting at the oil fill, and put a drain cock on one end. On the other end, a short piece of vertical pipe about 5 inches long will serve as the fill tube.
I think that's basically it. You might have problems with the governer being effected by gravity, but no one needs a governer anyway, right?

Ok i tried to twist the belt but it didn't work the belt was coming off the pulley everytime so i'm not gonna use that anymore. Now i was just wondering if i can modifie a vertical shaft motor to make it horizontal i hard people talk about it. If you can can you tell me the steps i have to go to make it THX.

Good page!
That's been a standard configuration for converting vertical to horizontal for a few hundred years, and it certainly works. However, there is one major disadvantage in the fact that you still need to add a clutch. That means putting the large drive pully on a jackshaft, and clutching the other side to the wheel. Another step, more belts, bearings, loss of power, etc. But it would certainly work.
One thing though: do NOT follow the advice to weld the pully onto the shaft. This is VERY BAD, and would make engine disassembly almost impossible. Proper pullies with keyways and set screws are easily and cheaply available.
