Engine Stalling, Surging or Running Rough
When your engine starts and stalls, it is often due to standard maintenance problems. Prevent stalling problems before they start with a tune-up kit. See “Why My Engine Won’t Start” section above or use the Q&A guide below.
Is your fuel fresh?
Stale, untreated gas begins to break down after about a month. Drain the gas from your lawn mower our outdoor power equipment, then replace with fresh gas and fuel stabilizer to extend the life of your fuel.
Is the air filter dirty / plugged?
Clean or replace the air filter.
Is the spark plug fouled?
Clean spark plugs where applicable (Follow instructions for checking and changing spark plugs).
Is your oil fresh?
Check your oil level and appearance every time you use your engine while it is cold. Your oil needs to be changed every 25 hours of use or season. (See Checking and Changing Mower Oil)
