I have an 1990 stihl 026 that i grabbed last year off an old farmer, saw was in great shape for the age and ran okay. Compression was a little low but above 100, without putting a comp test on it I do not know what it currently is. It starts and runs right now with choke then continues to run with choke off. Last time I went to use the saw was to go buck up oak 10" ish diameter for firewood, the saw bogs and wont keep a high rpm. I have requested a manual in another thread but thought that I would start this as there are guys who likely have an idea about what I need to do to fix this saw. Last year when I bought the saw, it got new end of line in tank fuel filter, air filter (mesh style) and plug. Now that it is bogging I am going to grab new fuel filter and plug. Chain is sharp and bar is in decent shape. I run 91 octane gas mixed with the stihl mixing oil at 50:1. Running winter weight bar oil at -5 C. Gas is two months old and my ms461 has no problems with it milling some of the same oak in the same conditions. (same bar oil used also)
To me, this sounds like a fuel problem of some kind or I need to adjust the H and L screws. I have no real experience tuning a chainsaw and appreciate any help.
