How to Convert a Lawn Mower Engine to Propane
Many automobile engines are using alternative fuels to avoid the high cost of gas, or for environmental reasons. Propane gas is cheaper than regular gas and burns cleaner. It is possible to change your gasoline mower to propane with a few simple steps.
What you will need:
Lawn mower, plastic tubing, duct tape, propane torch, screwdriver
Directions:
- Take out the gasoline tank and carburetor from the lawn mower using a screwdriver.
- Clip the nozzle off the propane torch. Make sure that you first take out the filter located inside the torch. Failure to remove the filter will reduce the flow of propane and prevent the engine from starting.
- Put plastic tubing on the open end of the torch. You can tape the area surrounding the connection of tubing and the torch with duct tape to secure it.
- Position the opposite end of the plastic tubing one to two inches into the intake of the engine.
- Use duct tape to fasten the propane tank to the lawn mower. It is usually best to place it on the lawn mower's frame adjacent to the handles used for steering.
- Start the engine, while making adjustments to the propane valve. You can adjust the propane levels until you can get the motor to idle regularly. Just make sure that you do not have too much propane flowing into the engine. This can cause a number of problems, including having the motor stall or rev up too high.
