Mobile Small Engine Carburetor Rebuild & Cleaning Great Falls MT
Is your engine surging, leaking fuel, or only running on choke? We clean, rebuild, or replace clogged carburetors on-site to restore smooth running.
About Our Carburetor Cleaning & Repair
Over 90% of small engine starting and running problems are caused by fuel system issues. Modern gasoline contains ethanol, which breaks down over time, attracts water, and forms a sticky varnish inside the tiny passages of your carburetor. This blocks fuel flow, causing the engine to stall, surge, or refuse to start without choke. Flying Wrench specializes in mobile carburetor servicing. We disassemble the carburetor on-site, clean all passages, blow out jets, replace gaskets and float needles, or install a brand-new carburetor if the metal is too corroded to restore.

Carburetor Cleaning & Repair Frequently Asked Questions
Common questions about our carburetor cleaning & repair service in Great Falls, MT.
Engine surging is when the motor revs up and down repeatedly. It means the engine is running 'lean' (too much air, not enough gas) because the tiny internal fuel jets are restricted by varnish. Cleaning those jets restores the correct air-fuel mixture.
This is a sign of a stuck float needle or a flooded carburetor bowl. Gas bypasses the carburetor throat and leaks into the air filter and crankcase. This is a fire hazard and requires immediate repair.
While cheap aftermarket carburetors are available, they are often cast from inferior metal and poorly calibrated. Rebuilding your high-quality OEM carburetor or replacing it with an authentic factory part guarantees long-term reliability.
