By taking these steps, you’ll effectively prepare your lawn mower for the application of WD-40 to its carburetor. This preliminary process will enable you to access and clean the carburetor thoroughly, enhancing the effectiveness of the WD-40 treatment and potentially resolving any issues affecting your lawn mower’s performance.
Applying Wd-40 To The Carburetor
Before applying WD-40 to the carburetor, ensure that the engine is turned off and has cooled down completely. Start by removing the air filter cover and air filter from the carburetor. Then, spray WD-40 directly onto the carburetor components, such as the throttle plate and choke mechanism, to loosen and dissolve any built-up gunk or residue. Use a small brush to gently scrub the surfaces to help dislodge any stubborn debris.
Once the WD-40 has had a chance to penetrate and loosen the grime, use a clean rag to wipe away the residue and excess WD-40. Take care not to leave any WD-40 in the carburetor as it can disrupt the fuel mixture. After cleaning, reassemble the air filter and cover, and start the lawn mower to check for smooth operation. Applying WD-40 to the carburetor can help to remove buildup and improve the overall performance of your lawn mower engine.
