Small engine repair at Josias Auto Service LLC is a fast, efficient service designed to get your equipment back in working order with as little downtime as possible. Whether you’re dealing with a compressor that won’t start, a portable generator that’s surging and sputtering, or any other contractor tool that runs on a small gas engine, we have the diagnostic experience to find the problem and the skills to fix it right the first time. For roofing crews and contractors who depend on these machines day in and day out, a reliable repair shop makes all the difference.

Common Small Engine Issues We Fix

Small engines are deceptively complex — even a minor issue can cause a complete failure to start or run. Here are some of the most common problems we diagnose and repair:
  • Starting problems / Carburetor cleaning — A gummed-up carburetor is one of the most frequent causes of hard-starting or no-start conditions, especially in equipment that sits between seasons or job cycles. We clean and rebuild carburetors to restore proper fuel delivery and smooth startup.
  • Fuel system issues — Clogged fuel lines, failing fuel pumps, dirty fuel filters, and stale fuel damage can all prevent an engine from running correctly. We inspect and service the entire fuel system to restore reliable operation.
  • Spark plug replacement — Worn, fouled, or incorrectly gapped spark plugs lead to misfires, rough running, and hard starts. We inspect and replace spark plugs as part of a standard tune-up or targeted repair.
  • Oil leaks and seals — A leaking crankshaft seal, valve cover gasket, or other seal can lead to oil loss, overheating, and internal engine damage if ignored. We diagnose the source of leaks and replace seals before they become bigger problems.
  • Throttle and governor adjustments — Erratic engine speed, surging, and poor load response are often caused by misadjusted throttle linkage or governor settings. We calibrate these systems to ensure smooth, stable engine operation under varying loads.

Fast Turnaround

We know that small engine equipment is often critical to your daily workflow. A compressor that’s down means work stops; a generator that won’t run means no power on site. That’s why we prioritize efficient diagnosis and repair — we aim to assess your equipment promptly, communicate clearly about what’s needed, and complete the repair as quickly as possible without cutting corners. Our goal is to minimize the time your equipment spends off the job.
Bring your equipment to us or describe the issue by phone — we’ll let you know what’s needed before starting any work, so you’re never surprised by the scope or cost of a repair.
