R3 Intake

If it really is an R3 intake, I don't think so. I don't think the R3 carburetors had a choke at all.

Looks like a repop - I have one with choke tube, 2 without. Teh ones without have no exhaust port in the center for carb heat, Bud Alenik claims this will make the carb ice up. I know that happens on airplanes, but can't imagine it in LA. Any thoughts?

Hmmm...it this were true, there'd be a million or two Chevy, Chrysler, Ford.....Studebaker...et.al, engines out there with the single plane type manifold (no heat cross over!) with iced up carburetors.

The only time I've seen this happen in my 55 years was on a then, friends turbo charged Corvair that he installed a standard down draft Carter two barrel onto the turbo. Out of the year or two he ran that combination, it did ice up one summer night. Just that one night. We never did figure it out.

Even on the coldest nights, I've never had a carburetor ice up, and I always block the heat cross over if the manifold has one.

I had a Ford with 2300cc 4 Cyl. The intake on one side of the head and the exhaust on the other. It would ice up esp when the temp was in mid to upper
