Stihl 032 Compresstion ?

[kidd300]

I got 3 032's and all of them with a car tester with the release valve ,all go around 75 to 80 lbs

is this normal all the saws pass the hold test and run great ?

i see some say 150 175 lbs how do you pull them to start ?

It's because you have the WRONG compression tester. Your results are not vaild.

Having the same problem with all my saws it struck me:bang: that with the length of the compression tester hose i was essentially increasing the cylinder volume equal to the total volume of cylinder and tube/gauge combined so by shortening the tube as above you will get much more accurate readings. the blue tube is 4mm rigid pneumatic tube which was pussed up inside the two off cuts of rubber tubing thus providing a means of reconnecting the two halves using superglue and also further reducing the volume of air required to fill the gauge.

You can just drill and tap the hole in the plug fitting, and screw in a bicycle tire (schrader) valve.
