My apologies if I this was answered previously and I didn't find it in search. Tuning my Jonsered 2152 and wanted input on the max no load rpm for high setting. A little info....I run 92 octane gas with additive to remove ethanol, strictly mixed at 50:1 with Husqvarna XP oil. Replaced the Cat muffler with a non cat version and saw wears an 18" bar cutting hardwoods 90% of the time. I have tuned by ear and feel I have it 4 stroking fairly well at full throttle but my Obsessive Compulsive Disorder will have me checking with a tach tomorrow for the finest adjustment I can get...just don't want to run the risk of going too lean. Thanks in advance for the advice
