Convert to replaceable idle air bleeds?

I see nothing wrong with drilling and tapping your blocks unless you want to save them in original form because whatever.

As I posted in the ignition timing (+ carb) thread, I decided to go for it. Main body and secondary block are now converted to 4-corner idle :)

If you want to buy shiny new aluminum throttle plate, find out which ones come with reasonably sized transfer slots. IIRC Jmarkaudio posted that QF are pretty good that way

Yep, got a shiny new Quick Fuel 12-700 and also plugged the dribble holes at the bottom of the transfer slot bore.

Now that it's all together, I'm thinking I should take it all apart again and do the replaceable air bleeds, at least for the idle circuits. I never noticed how much smaller the secondary IABs are than the primary until it was pointed out on tapatalk/racing fuel forum.

Any idea what size to make them (assuming all four the same)? If they should be .070 like the primary ones, I could just pull off the secondary bowl & block and drill the pressed-in ones to size ;)
