Choke/No choke

(1/2) > >>

Bills64:
If running 98% on the street (daily driving) and 2% at the strip, would having a choke on a 17057274 cost big et's?

Kenth:
Very little if anything, but not adjusting the stop to the air valves for maximum degree of opening does.
1.38" measured from rear edge of open valves to back of chokeblade housing is max, then the valves block fuel flow from the nozzles.

HTH

Bills64:
Hopefully 1 last question. On this 17057274 carb is it necessary to hook up the rear choke vacuum canister or can it be bypassed? If it does need to be hooked up, what vacuum source? I'm converting to an electric choke.
This carb is not in the original car.

Kenth:
You can toss the secondary chokebreaker, it´s an emission device for finetuning the choke function and not really needed for performance usage.

Bills64:
Thank you!
