Frequently Asked Questions

Why do I need a specialized carburetor adjustment tool?

Modern small engine carburetors often use tamper-proof screws (like Pac Man or Double D shapes) to comply with EPA regulations. Standard screwdrivers won't work. These specialized kits provide the necessary bits to fine-tune the air-fuel mixture for proper running.

How often should I use an engine compression tester?

A compression test should be performed whenever an engine exhibits symptoms of low power, rough idling, excessive oil consumption, or difficulty starting. It provides a quick, non-invasive way to assess the internal mechanical condition of the engine.

Are cylinder honing tools difficult to use?

Cylinder honing requires care, but basic deglazing tools (like the adjustable 3-stone hones) are straightforward. They attach to a standard drill and are used to create a cross-hatch pattern, which is crucial for oil retention and proper piston ring seating during a rebuild.
