According to Mikes Carburetor the power piston spring is no longer available. However I found a kit that includes the spring (about the size and twice the length of a ball point pen spring). The companies name is "The Carburetor Doctor" in Canada but, they don't ship out of country. If I get desperate would it be possible to have one of our brethren order the kit and then send to me. All expense paid plus your time. Oh by the way it's kit #CK10, $34.42. Doc.
