Need help dialing in dual 38s on superjet

[Chett6.7]

I have a 61x cylinders on a 62T case, ported by the use of yamanubes exhaust porting template, boredddddd to 82.5mm. Everything else is stock. Does anyone have a recommended idea how much the low and high fuel mixtures screwed should be turned out?

Generally I start out with 1-1 1/4 turn on the low and 1 1/2 turn on the high. Also make sure both carbs are synced.

What is your jetting? Pipe?

Stock Jetting has stock pipe

Ok, I would start with 1 turn on the low and 1 1/2 turn on the high as a staring point.

I might try 75 low jets with a ported cylinder
