Building a go-kart using an old mower engine isn’t so easy of a job as it might sound. That is because karts and mowers are built differently. To use a mower engine, you will need to make some adaptations. Once you’ve done so, however, you can build a go kart for a relatively tiny amount.
Lawnmower engines are designed with vertical shafts. To convert them for go-kart use, you can’t just tip them onto their sides, because the oil in them wouldn’t be ready to circulate to lubricate the engine properly. You’ll need a gearbox that will convert the motor you’ve got to one that may operate a go-kart. As you can see, this is going to take some experience, and an amateur engineer probably isn’t going to be ready to handle the job unassisted.
Here is one method of changing a lawn mower engine into one that may work on a go-kart. First of all, you need to put a gear on the base of the engine that will turn gear that turns the spindle. If you are like me, you would not have an idea how to do that and would wish to hire it done ; however , with one or two mechanical talents or a friend who knows about engines, you should be fine with this step. What you are needing is bevel gears with a disengage lever to split them. You may also need brakes that may activate whenever you pull the disengage lever. Lose the choke. Instead you’re going to need a gas pedal which can be installed on the floor of the kart near where your feet will be.
If you decide to look online for information regarding changing a mower to a small go cart, you’re going to find a lot of conflicting information. What one person will tell you to do contradicts the recommendation you get from someone else. One website recommends the strategy listed above while others swear that it’ll never work. Therefore, unless you have basic mechanical abilities and knowledge, or you like to mess around and see what you can come up with, you’ll probably be better off getting professional help or buying a ready-built go-kart.
