So ive been given a nrand new pittsburge compression tester from harbor freight for free. I figured what the hell I'll take it and tried it out on my saw. compression came in at 15PSI on a 40cc husky and 60PSI on a 7900. I know this is wrong as both the saws still rip with plents of pull. I'm pretty shure I'm missing the Schrader fitting to make this tool applicable to chainsaws. Can anyone post an adapter or connection peice to make this tester work on saws? Or should I just buy a new kit?
