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.

Common Questions About Engine Repair

Most minor repairs like carburetor service or spark plug replacement can be completed within 1-2 days. More extensive repairs such as top-end overhauls or transmission work typically take 3-5 days. We'll provide a more accurate timeline once we've diagnosed your specific issue. In many cases, we can complete same-day service for simple repairs.
Yes! We stand behind our work with a 90-day warranty on both parts and labor. If you experience any issues related to the repair we performed within 90 days, bring it back and we'll fix it at no additional charge. This warranty demonstrates our confidence in the quality of our workmanship and the parts we use.
We service all major small engine brands including Briggs & Stratton, Honda, Kawasaki, Kohler, Tecumseh, Craftsman, Troy-Bilt, Husqvarna, John Deere, Cub Cadet, and many others. Our technicians receive ongoing training on new engine designs and service techniques to ensure we can handle both classic and modern equipment.
Repair costs vary significantly depending on the issue and the equipment. Simple tune-ups start around $89, carburetor service typically runs $99-$179, and major engine work like piston replacement can range from $299-$599+. We always provide a written estimate before starting any work, and our diagnostic fee ($99) is waived if you proceed with the repair.
This depends on several factors including the age of the equipment, the cost of repair versus replacement, and your needs. Generally, if the repair cost is less than 50% of the cost of a comparable new machine and the equipment is otherwise in good condition, repair makes economic sense. We'll honestly assess your situation and provide a recommendation—we never push unnecessary repairs.
