Carb settings

[thetoolnut]

I was given a Jonsered 2150 to service and the last part is tuning the carb, I have a Tinytach wireless tach and I have her running at around 2,500 rpm's on idle and 13,900 rpm's with the throttle wide open. The idle and pick up feels and sounds good so I'm happy with the idle and L jet, I just need advice on the H jet.

 

Thanks lads.

Max rpm is 12.5k so wind the h out anticlockwise. I usually set it 500 -1000rpm below max.

 

Don't hold the throttle open for too long, just raz it up see where it is and let it go down.

 

YouTube is your friend, it certainly helped me.

Thanks for the input, i turned the h jet all the way anti-clockwise and adjusted the l jet and idle. She's idling at around 2,600 and the pick up is good. Max rpm recorded on the tach was 12,750 or there abouts. The litmus test is putting it through some wood of course,

 

Thanks.
