e85 Air Bleed sizes

[s10360]

I have a proform 750 with quick fuel metering blocks, and don't know what air bleeds go in it. I know .028 but don't know the other size . For some reason I'm thinking .061 is what was in the home built one! Please help as I'm stuck . Thanks for your time guys I know you've been asked this 4 billion times

Welcome S10360.
The size of the IFR plays a role in the size of the IAB. The .061 is ok to start with as well as the .028 for the HSB.

60-65 IS A GOOD START 25-28 ON HSB
