  If your RedMax Trimmer engine is hard to start, several issues could be the cause. It might be due to a stop screw for the throttle that isn't working correctly, so check its operation. Other potential causes include a blocked fuel filter (clean or replace it), a blocked fuel hose (inspect and clear it), or air in the fuel pipes (bleed the air). The issue might also be incorrect fuel (use proper fuel), a defective or worn needle valve (replace it), a damaged lever arm of the needle valve (replace it), a lever arm that does not operate correctly (adjust it), a damaged control diaphragm or defective seal (replace them), or a blocked needle valve or object in the needle valve guide (clear the valve or remove the object).
