Which main and air jets for a 2165 CC with IDA'S

[Frenchy Dehoux]

    Well I finished building my fourth motor in 2 months . First one a 1835 CC with 42 DCNF 9 Webber the second motor a 2332 CC with IDA'S . Next one 2276 CC .Now I need a break before going to the Bug - In in a week. But my last motor is a 2165 CC with 48 IDA'S I have a turbo cam 1.4 rockers with straight cut gears 42 x 37 valves with an 0.10 for now but it will have a Joe Hunt magneto before too long and a Berg fat pulley. Any one with this combo give me an idea what you have for main jets air jets venturi etc it has 8.5 compression.

    Thanks

Ta get you in the ball park, try 40 vents, 60 idles, 155-160 mains with 200 airs.

I was thinking Frenchy could stick with the 37s and go 155M, 180A and yes 60 idles to start.

Dang you guys are fast! Looked away to do a few little calculations and there were already two responses

I second the 155 main and 180 air to start with.
