I have an old stihl 025 that I bought new back in around 2000/2001 and it has been a good firewood saw for me. I have acquired a few more different saws and thought I should pick up a compression tester and see where they were all at. I bought the innova 3614 tester. I have a Stihl 025/16", MS362/20", 044/24", and a Jonsered 2051/18". I just did a carb kit on the 025 and the 044. These are the results I got:
Stihl 025 compression was 90 (first test I did, warmed the saw up and had the air cleaner off)
Stihl MS362 compression was 120 (cold, air cleaner on) (I bought this one used)
Stihl 044 compression was 145
Jonsered 2051 was 152
The reason I did the carb kit on the 025 is because it wouldn't stay running when it was warm...if I set it down it would die and then be flooded and hard to start. I'm thinking I wasn't supposed to warm it up to do the test, but wondered what the rule of thumb is on that. I will have to try it again cold.
Is 90 quite low even warmed up?
The 362 runs good, but is 120 a little low? Paid $375cdn and it has the extra handle and heated grips and carb so i think it is worth keeping.
Thanks for any input!
