This modification is a little more than I would be able to do myself. However having said that, won't venting the carbs do the same thing? Or am I confusing two separate issues here?

Two different problems.

The Vent Tube.. EXTENSION... just keeps the fuel from sloshing OUT of the carb...


Jet Relocate is to keep fuel over the jet in hard cornering... when it sloshes!

Can someone recommend someone that can relocate the jets? I would prefer to just send in the bowls and have it done than try to do it myself.

Michael LeVeque did a set for me. Marty also mentioned above that he has done it, but don't know if he does it for others.

Yes, I occasionally do carb mods (as well as engine work) for Corvair owners.

Good morning. I have an extra set of carbs I'm going to make this mod to. I had a great time autocrossing my car for the first time this fall. However, to be more competitive I realize this is a necessary modification. Does anyone have the specifics as far as tap size for jet, hole to plug on outside and what you are using to plug original jet hole. I can measure threads off my own jets and go from there but if someone has detailed descriptions on performing this it would be greatly appreciated. Thanks

...a looong time ago Dave Clemens did a pair of carbs for me but I did find out that the old main jets and their holes were 1/4-28 thread...I wouldn't try this myself tho

Davemotohead, my take is that this jet relocation serves the same purpose as rotating the carbs. 90°. Without all the linkage refabrications.

Rotating the carbs is the best choice IMHO,not only do you get the jets in the right location you also get the float to pivot correctly. The Rotated linkage is actually simpler than the stock set up. Bill Thomas was no dummy smiling smiley Billy Bruce has a Thomas set up on his track car,very nice. Mike

Thanks Mike. I'm using the RP linkage and I like it quite a bit. My goal originally was to rotate and I have a set of rotators but RP did not have the linkage design for that yet. I asked him way back before I started building this car. He may have them now? With some extra carbs lying around needing rebuilt, I figured I would just relocate jets for autocross.

Recently completed set that is for sale. Vents fit under a stock air cleaner.
Note that one jet is NOT on the power valve side, so that both jets are to the rear, so the fuel covers the jet under acceleration.
Carbs properly jetted , especially with a performance cam do NOT need the power valve.
GM did that to prevent top rpm lean mixtures on stock Corvair that ran at high speed for extended periods [ mostly 140 equipped cars, I suspect ] with very lean main jets.
Similar secondaries can be provided.

Fully street-able.
Includes choke pulloff units.
LMK of any interest via PM.
Sold outright, no cores needed.
Yes I can do this modification on client carbs.

Bob, I thought the vent tubes were put into the small holes that lead to the top of the fuel bowl. Yours seem to have the vent tube in the duck bill, which leads nowhere. Can you clear this up for me? I'll PM about price for these.

You can always drill a hole...

The vents have been filled - see pic.

The single vent has been written up somewhere - Comminques?

Not sure of the advantage - other than stock air cleaner can be used. And, the vent is in the center / side of the fuel bowl

Early model carbs have the bowl vents in the duck bill, most racers prefer the early carbs as they do not have the PEV plumbing and are easier to relocate the jets and bore the venturis out larger, the extended vent tubes are to keep fuel from over flowing into the carb throat on long or hard turns with G forces.
