Stihl service tool question.

[Nicholas]

I just purchased a flashy new STIHL compression tester to add to my collection of service tools. The only problem is the compression tester is set up for 4-mix engines. Would anyone know... maybe Lakeside would know... if there is a special 14mm test adapter available to compression test normal 2-cycle saws, trimmers, etc? I can't find anything in the special tools manual. Maybe I am not looking in the right spot. If nothing else, I'll contact STIHL Midwest tomorrow.

Thanks,

Nick

You can get that 14mm adapter off Mac or Snap on and most any car parts place. Stihl can get it for you as well..

Wow, someone actually bought the Stihl tester?

I got my tester at AutoZone and it came with a 14mm adapter

i had one for auto use, but when i put it in my poulan pro saw the adapter was too long and the piston brought up on the adapter----the reach was too long. quick adjustment with hacksaw and file and all was ok....

If possible you really want to get a gauge without an adapter... and one the shrader valve right at the tip. If you adapter has say 3cc of volume, and your compressed cylinder volume is 6cc... your gauge will read way low...


I use mine without an adapter on the small cylinders, and adapt UP to the larger (like my truck)where the volume error is tiny.

In your case, go for the smallest adapter you can find..

I was thinking of trying this. A old buddy motorcycle mechnic told me to I could make my own adapter by breaking the porclein insulator out of a spark plug, and drilling & tapping the metal portion. Sounds like a neat idea to me. But, I wonder how difficult it would be to break all the porclein out cleanly without destroying the metal portion of the plug?
