Makinakart
I have a Sears craftsman push lawn mower engine and I'm going to be using it for a go-kart , which is for a physics project. I know I know, I should go buy an engine, but I have a strict budget with the class and I would really like to turn this engine sideways. So far I can see that turning the carb around should be easy. I'll just make a little mount for it and put some tubing to extend the fuel to where the spark plug is. But, one concern I have is with the oil distribution if the engine is sideways. I really don't understand how this oil gets dispersed and maybe, with a better explanation I could come up with a solution. If anything I'll make the engine rotatable on the kart, and turn it back to its normal position when idling:P Anyways any thoughts on fixing this oil problem? (even though I don't even know if I have an oil problem).
-I forgot to mention that the oil is seperate from the fuel tank, and the fuel tank is gravity fed. The reason why I haven't tried is because I'm still working on getting the blade off. From what I've heard gearboxes are heavy and will result in a loss of power. What if I just overflow the oil container to way past the amount recommended , then when I turn it sideways more of the parts will be submerged?
- I also think its about 5-6 hp in comparison to a 3.5 I have lying around
-It also has an internal reducer that comes out horizontally for the self propelling part,
-Could I take the internal reducer off? so that that axle spins the same speed as the blades, then just mount the engine straight?
Answer
Hmm I'm not a motor type, but assuming it is a cheep small engine and as such the oil is probably gravity fed. If it is the problem in addition to possibly leaking oil like a siv in to the pistons/piston on the lower half of the motor is the pistons/piston on the top side not getting any lubrication. If it where my project I'd leave the motor orientation the way it was designed for the mower and use gears to change the direction of force it generates. Not sure the added weight of the gear housing (safety don't want to fall in to the gears) would help you go-kart go with a small motor tho.

How Can I Use A Lawn Mower Engine To Power A Go Kart?
billy the
I am 14 years old and trying to make a cheap little go kart. I am using wood to build it so it is not very complicated, but I do not have the funds to use a horizontal shaft motor. Do you have any ideas of how I can make it work???
Answer
Changing a horizontal engine to a vertical engine is not the easiest, nor inexpensive task. Changing it requires 45 degree gears which are expensive and may not last long (depending on manufacturer and intended purpose). You are better trying to find an edger gas engine (although lower horse power than lawnmower), a tiller (which some that have more HP than lawnmowers).
In addition making the frame out of wood spells disaster. It may be strong enough for a while but with time it will come apart (most likely on a turn). As I was younger I looked into making a go kart and putting it together from scratch it is not the most economical way. Trying to get one used is definitely cheaper unless you can weld your own parts. Another way to look it used is by buying used parts and put it together.
By the your question I can tell you are looking at 1 problem and not thinking of the rest.
Do you have the entire plans for the go kart.
What are you going to use for wheels?
What type of braking system you are thinking of?
How about clutch? (lawn equipment usually does not have or require any so the engine do not have any).
What is your budget?
No matter what it is not a $20 project.
BTW, check out ebay to see what parts are available and how much used parts go for.
For instance a full (cheap) go kart goes for $340.
A new go kart nice 90cc full cage kart goes for $900.
Hope this helps
