Carburetor Rebuild or Replace? – How to Choose

Dirt, bad gas, varnish, and corrosion are popular evils that can clog and wear down the carburetor on your lawn mowers, chainsaws, and other small engine equipment.

If you’ve diagnosed your equipment and found carburetor problems to be the root of your engine troubles, you have two choices – Repair or Rebuild.

Your choice whether to rebuild or replace the carburetor depends on your technical skills, budget, time, and the extent of damage to the carburetor.

Always check the price of a new carburetor. Sometimes, just a few more bucks spent on a new carb assembly can save you the workload of overhauling and cleaning your current carburetor.
