My friend has a go cart with everything but the motor in it. I want to put an engine in it for my son. The go cart is just an old honda 3810 riding lawn mower stripped down to the frame and the essentials. The lawn mower has some kind of transmission in it and it has a clutch and a break in the same pedal. I don't want an engine that will pass cars on the highway. Just something small that will go anywhere from 20 kph to 50kph. So if anyone could tell me how big and what kind and even what modifications I might need to do to the lawn tractor that would be great. Im NOT looking to buy a brand new engine…Just looking to find a used one that I could salvage off of something else. Thank you for all feedback!


Most of the go karts I have seen use either Briggs & Stratton engines or Robin Subaru. Robin Subaru makes a small engine especially for Go Karts. You may be able to speak with a small engine repair shop close to you to find out which engine will work best for the machine your are trying to build. They may even have some used engines around.

Here is the First Part of my Go-Kart build. To see the engine running right out of the box, check my other videos.
If you have anything ideas or things i should know about building a Go-Kart please leave a comment.

Go kart frames

Go karts are a kid’s best way to challenge their racing ability on any circuit. The best way to determine which kind of go kart frame you will need is have the person who is going to be driving it sit down and have you draw the frame around them. This will help ensure that they are comfortable while driving and riding; a chalk outline will help you with the measurements. A wider wheel base will make a more solid go kart frame, if you just want a street go kart then allow for a wheel base that give the driver more control. If you want a racing go kart then you will need to design a roll cage.

Cut out the tubing and lay it together, you will want some flexibility but make it solid so that one side does not suffer stress and cause the rest of the chassis to break apart. Use a tubing notch to make sure that all the pieces fit together and that it’s sturdy enough to hold an engine and steering wheel. Keep a solid center of gravity, the driver must be safe if you decide not to install a roll cage.

Once you have pieced the frame together you will need to weld each piece, if you have a metal inert gas welder then you can construct a sturdy solid frame. Once you have let all the welded pieces cool down have the person who is going to be driving sit in it and note any stress factors and correct them.

If you are new to go kart frames you can visit a local track and see how they are constructed, they might even have some broken frames that just need to be fixed and you could save some time and money that way. Building a go kart frame can be fun and if you want to see how the better ones are built many times the mechanics who service these fun machines will show just how it’s done. Keep in mind that the person who will be driving must be comfortable in the driver’s seat.

If you plan to race go karts then you will need to have a better understanding of the circuit and which type of chassis are the best. A hand built go kart might not be the best in this type of environment; you don’t want an accident with a poorly built cart. Check the rules before submitting your kart; the whole premise is to have fun but to be safe. Different frames are designed for different kinds of tracks. Dirt, asphalt, and concrete put stress on frames differently, make sure you have the right frame for the surface.

i don’t know anything about i just want a basic go kart frame that most engines will fit in strong an efficient… can you tell me what i should do please ?? any good information will be grateful…
and would a 100 amp arc welder,make the frame strong with good welds?

well, you need metalworking and welding skills first. Usually when i want to build something, i look at all kinds of the product from different companies and find out why they were made in the way they were. Some type of frames might be stronger, some more stable and so on. Do that, and after a while an idea will just kinda pop into your head about how to do it.

I need to a go kart frame for $40 or lower somewhere within an hour of central PA
i said $40 dumb-ass
and i don't care what catagory its under!
as long as its answered

ebay or craigslist, ive bot 2 go karts with good running motors for $100-150 on ebay

Stripped out parts from an old car: Engine, transmission, and drive shaft (RWD). This chassis and frame is taken out of a R/C car, but if enlarged would it work for this situation? Would this idea really work? http://img296.imageshack.us/my.php?image=bajaideayd8.jpg

(quick sketch on paint sorry)

If you scale up from an R/C car the chassis will be too bulky and heavy. For a good kart chassis you need strong tubing. Cold worked steel tubing will work but moly steel is better. I would suggest you buy a second hand chassis. It will be better and much much cheaper. Believe me I have built one from scratch, it was not easy.

aluminnum pipe is best then mild steel depending on weight needed

I just recently finished painting my go kart. Ive been working on it since 2005/2006 when I bought the frame. Ive done some mods and im currently buying parts for the engine to get more hp out of it.

Enjoy..
