Allstate carburetor

Allstate does have their side but the fact is= they will never tell you the truth!! I'm glad you got the street avenger with the straight leg booster and should work just fine. I know this because I'm the guy that did the R&D to figure out that the calibration on the 670 idle to transition circuit is lacking in fuel volume. I figured this out- NOT Jim from Allstate !! That company is only riding on the coat tales of my 20 yrs of intense work. Somebody mentioned what was done to correct the off idle stumble- no problem, here it is.
80670
Primary Idle air .070
Primary idle Fuel .031
No Jet Change
This is the correction for fixing the 80670 Street Avenger.. No secret.
Like I already stated- I was the High Performance of Allstate Carburetor
I got Allstate hooked up with Barry Grants to do all their rebuilding, I did this for 10 yrs
I built Carbs for Dyers SuperCharger Company for awhile
Jegs and many more
The Holley Performance account was landed by me and I set Allstate Carburetor up with Holley as a direct buyer..
Not sure what Jim told you but I'm sure it wasn't the truth. Where do you think the name Competition Carburetor came from - Jim "THE OWNER" threw me to the curb and thought they would get away with it (poor character) I never thought I'd be going head to head with the company I developed, Allstate Carburetor is just a name- what good is a name without the knowledge to back it up, watch the steady decline- "NO Man is an Island" to much money in the wrong hands will make a person do stupid things... Go to Ebay and search for my user ID competitioncarburetors click on the "ME" icon next to my user name and you can read more indepth about my history.... That being said- Your 670 purchase will probably be just fine. I just need to get the truth out.. they started to sell 670 street avengers with down leg booster on Ebay and It doesn't matter if it's a race application- it will be an over fuel.. That's it! Booster signal strength has a direct corallation to venturi size. A 670 street avenger has a small ventruri, (the smaller the venturi the faster the air speed) Booster are activated through air speed- so putting a down leg booster into a small cfm will pull fuel immediately and with great strength- this will also equal out to more fuel volume. Reason for this is a venturi has the shape of an hour glass so the deeper you can get a booster to the norrowest point in the hour glass the more sensitive and aggressive it is. My purpose off jumping on this thread was not to bash Allstate- but to educate those and inform the buyer of the 670 about what I saw on Ebay as a problem carburetor being produced by them, Maybe they stopped selling it like that, I don't know..
