Common Engine Problems We Fix
We've seen just about every small engine issue imaginable over our 13+ years in business. Here are some of the most common problems that bring customers to our shop:
Won't Start: This could be caused by a dead spark plug, bad fuel, a clogged carburetor, or compression issues. We diagnose the root cause and fix it right the first time.
Runs Rough: Uneven running often stems from carburetor problems, dirty air filters, or worn spark plugs. We'll get your engine running smooth again.
Loss of Power: If your equipment isn't performing like it used to, we check for worn piston rings, clogged exhaust, or fuel delivery issues.
Excessive Smoke: Blue or white smoke indicates different problems—blue means burning oil, white often means coolant leaks. We identify and fix the source.
