PATRIOT BP 41 Chainsaw Cold-Start Knob With Grommet

This cold-start rod / lever fits Patriot BP 41 and many other chainsaws. The rod links the external cold-start lever to the fuel enrichment valve inside the carburettor, letting the operator restrict incoming air to enrich the fuel-air mixture for cold starts. When the rod bends, its linkage pivot wears, or the lever breaks, the enrichment valve may not open or close fully, leaving the engine either flooding with the valve stuck closed or failing to start in cold conditions with the valve stuck open. Fitting a replacement rod restores proper cold-start control.
