Have several old pOULAN 3400,3700 AND 4000'S. Does anyone have an idea as to max rpm? My service manual only shows idle RPM. I've adjusted hi-speed needle to where it tops out @ 12,500 to 13,000(checked with Tach) with bar and chain no load. I'm uneasy about leaning it out more as manual advises against going less that 7/8 of a turn. Seems to cut okay w/o bogging so maybe 12,500 is all I can expect.
