E85 main jet for a 900 cfm flowed Anullar carb?

Post by NXBOY » Thu Jun 14, 2018 1:52 pm

Hi, first off I built this 9380 yrs ago with some help and did the basic enlarging of passages like was told. .160 angle in the Qiuck fuel blocks. Have to pin the boosters there .160-180 size. Did the Idles restriction and the Idle bleeds. Car started great and revved good and criused aroung good. But had it on a engine that had bad cam and lifters mushoomed so it was way down on three cylinders. Thinking like I had it like 89 with front power valve and 98 rear without P/V. Just like a General Idea what should be close. Can PIN any passage if ya like to help get it dialed in. I blocked center emulsion jet in block so it wasn't over emulsified as heard E85 doesn't like TOO much. Thanks.

Thanks I built this type Carb for only like low 6 to 6500 rpm, maximum torque type motor with a RPM intake and tight LSA. I expect the Annular to run a little richer at higher RPM. How would you jet ? For E.T or temperature rise down track?
