Looking for a decompression valve and washer for a P60 that I am saving from the junk pile. I am not having any luck and was wondering if anyone has modified a Stihl or Husky decomp to fit. I know the threads are different standard vs metric but has any one tried welding the threads on a husky valve and then use a die to cut the threads to fit the Pioneer? My guess is the heat would destroy the decomp valve? All thoughts and ideas would be appreciated. I do not really want to start this beast of a saw without a decomp valve. Thanks
