1) choke kit 45-223 & 45-224 manual to electric automatic, I bought a Holley book & it says 45-223 for the 3310-1. I installed a choke kit the speed shop gave me last year I'm not sure what the part number was but it had the rubber vacuum hose which I didn't need, which makes me think I may have the wrong kit 45-224. What is the difference in between the two kits? Are the choke housings the same? Could I get a vacuum leak if I had the wrong choke housing?

2) From the book "electric heating units are used in some integral chokes to preform total heating function in place of hot air" Is this what I have? because I don't have any heat tube from the exhaust maifold.

3) What is the dashpot for? and how does it work? My carb does not have one, should it?

4) There is a graft in my book Accelerator Pump Capacity With Different Cams, this graft was made from tests of various cams run with a high capacity pump(50cc per 10 strokes maximum), clearance of 0.015" on pump lever at WOT, and constant idle air flow. Capacities are in cc's per 10 strokes. The graft has a blue cam in position #2 with a capacity of 20cc's. To me this is 2cc's per squirt (2X10=20). My question is if that blue cam is used in position #2 with a small pump (30cc) will the capacity be less than 20cc's? Dave

I just contacted Holley about that identical choke question. In my case, the carb is an e-Bay 80508 that had been converted back to manual choke. The 80508 is functionally identical to the 3310.

You have the choke kit for EXTERNAL vacuum source. You need the kit for INTERNAL vacuum. The vacuum source for the 3310 and 80508 is right on the side of the carb, sealed with a tiny o-ring. (cork, I think.) No vacuum hose needed. And, by the way, a dandy place for a vacuum leak if you aren't careful with the choke installation. The vacuum operates the internal pulloff, without it the thing is gonna run VERY rich when first started.

Yes, the electric heater takes the place of the hot air supplied by the manifold.

Dashpots are used on cars that tend to die when the throttle is released suddenly. Generally auto transmissions. You "probably" don't need one. If the car dies when you pull your foot off the gas from fast idle, put one on.

I don't know what graph you're looking at, but yes, the small pump will provide LESS fuel per squirt than the big pump. First guess: About 3/5 the fuel.

Schurkey thanks for the info, that helped alot. Do all chokes with the electricial hook up have the choke heater? dave

Yeah, that's what the electricity is for.
