4150, 3 circuit carb question

[bones]

hello, I have a Promax 4150, 1050 cfm 3 circuit carb I trying to tune, not ever played with a 3 circuit carb before, how do you make adjustments for the idle circuit and the intermediate circuit?


thanks

The intermediate curcuit has a pick-up and restrictor on each side of the metering block. The fuel bowl side acts just like a jet. On the idle curcuit there is a restrictor for it as well (larger size hole = richer idle curcuit). I hope this makes sense and helps out.

Thanks

thanks Ben, on the fuel side...working from the main jets out, next would be the intermediate, then idle ?

and the air bleeds in the main body...upper one intermediate
lower one idle?
