Hello David, Thank you for your inquiry. Check the throttle bushing, the valve stem, and the throttle spring, as if any of these parts are damaged or stuck, it can cause the ratchet to run all the time. Remove the roll pin from the lever as well and check for any debris that could keep it from closing off the air. Check the air intake as well for any debris and put a few drops of machine oil in it to loosen it. Good luck with your repair.
All our customer repair instructions are solicited directly from other customers just like you who have purchased and replaced this exact part.
Air paddles were bad and throttle valve was missing.
