Lostforawhile I have heard different reasons for there being 2 vacuum ports on the distributor and not sure which is correct? I am assuming your correct in stating that one just retards timing on start-up and doesn't really need to be hooked up full time. With that assumption can you please tell me which port on the distributor is supposed to be hooked up to vacuum all of the time? Toward front of motor or rear? No one can seem to say which needs to be hooked up to vacuum full time? The hesitation at 3500 rpms or so does feel timing related more-so than fuel and if the dizzy is hooked up wrong well there I go. I would really appreciate if you could tell me which one is the correct one to have hooked up?
Roodoo as far as running out of fuel like with a Weber this one doesn't do it. I have a center hung fuel bowl which is the same setup I run on my Ford Mustang 4 cylinder I use on the circle track which obviously gets a lot more jostling around than our street machines.
I think with the TV cable I'm not having to accelerate as hard as I did with the OEM carburetor or the Weber and that's why I'm not having problems? With the Weber and OEM carburetors I was at 1/3 to 1/2 throttle at 60. I don't even give this Holley half throttle to get going unless I'm hot dogging it and cruising at 60 I'm at about an 1/8 of throttle. There is the difference probably? I used to get the kicking in and out on the converter with the OEM all of the time. The Weber well I didn't keep that **** on there long enough to notice but it probably would have too.
I feel the Holley 2300 series is a far superior carburetor. I know some people will say otherwise but that's my opinion and I've had both, just on this Honda as a matter of fact, and there is zero comparison. The Holley runs a lot better. The Weber did have good acceleration from a stop and that's all I can give it. However, overall running down the road the Weber was worse running than the OEM carburetor. Seriously!!!! Maybe I got a bad one but if that's the case every one I've ever got has been a bad one.
I know people will think I changed a lot of stuff to get the Holley running right but I didn't. I made an adapter plate took the carburetor off of my race car and bolted it to this Honda and it ran perfect. As a matter of fact on a dead stop it would squeal the front tires. The 350 cfm street carburetor I have on it now won't do that but I'm not complaining this carburetor runs, drives, idles and accelerates very well.....but it's no 500 cfm race carburetor . However, I'll take the 350's fuel economy over the 500's sheer power any day. Plus I am still tuning on this 350 when I got time to so I'm not done. My race carburetor on the other hand well I've had lot's of time at the race track to get it dialed in to be very responsive to foot input plus that's what it's made to do. The 350 is supposed to be a good running street carburetor and that is exactly what it does.
I remember someone saying I would get awful mileage and no drive-ability out of this Holley. I'm not picking at you by any means but not only have I gotten good mileage but I've exceeded, by far I may add, the mileage I got with the Weber. I'm getting better mileage with this Holley in town than I did with the Weber on the highway for the 3 or 4 god awful weeks I had it on there. Drive-ability well like I said earlier in my rant ZERO comparison. The Holley is far superior, in my humble opinion, in every way.
Thanks for your comments and suggestions guys hope one of you can tell me which vacuum port on the dizzy is the right one to have hooked up?
