I have a question about a Jonsereds 90 that I hope can be answered!
The saw looks and runs great but I had to clear yrs of chip and dust from the recoil/cylinder fins.
I put the carb through the ultrasonic cleaner and rebuilt it with an OEM RK23HS kit but I can't get the saw to tune below 12k rpm and according to the Acres site its max should be 10,700.
Does the carb have an internal governor?
I'm wondering if the cylinder was overheated and letting in air because it runs fine then will take off to 12k.
The crank seals were fine when I put it on its sides.
