- Make sure the carburetor kit you ordered is correct for the carburetor number you have.
- Read the instructions that come with the kit then take the carburetor off the tractor and disassemble it. You may want to make notes or take pictures of how it came apart.
- Be careful when taking the jets/nozzles out as they like to twist off and can be lost.
- If the jets/nozzles are frozen in the body rinse the carburetor in water to remove any gas vapors then use a small torch to lightly heat up the old screws and plugs, then drip candle wax around the threads to help loosen them.
- Clean the separate parts, you can use carburetor cleaner to soak it, or if it is really corroded use a sand blast cabinet to blast the rust etc. out of it, either method will work.
- Next run a small piece of wire or a drill bit through all the passages to finish removing any debris that may be stuck. If these small passages are plugged the carburetor will not flow right.
- Use air pressure to blow all the debris out of the passages you just cleaned. If you are planning on using the old float test it by submerging it in a container of hot water, if you do not see any bubbles after a few seconds it can be used.
- Lay all the parts out that will be replaced and start reassembling the carburetor. You will need to adjust the float lever (measure the distance form the flange of the carburetor to the closest part of the float by bending the flat part of the float bracket) after installing the float you can finish assembling the carburetor. Make the initial adjustments per the instruction sheet.
- Install the carburetor and check for leaks and test run it. Make the final adjustments while running.
Good Luck!
