Edelbrock AVS, or Carter Termoquad????

The thing about a TQ is they must be set up right to start with. There are many little adjustments/specs to be met first. Theres alot of external mechanical linkages that need to be measured and adjusted if need be to what there spec is. The adjustments are easy to make and over do, so take your time.

Make sure the throttle shafts do not leak air or fuel. You can or have done for you, is to rebush the shafts. Demonsizzler above does reallllllly nice work. So, if you should feel so inclinded to pass work along, he's my guy to work on stuff when a simple rebuild is more than my carb needs. (I just do not have the tools and would rather pay the man to be honest with ya.)

I have run the AVS before and think it a way better unit over a AFB.
I switch outa AVS to try out a TQ and I like that carb a whole lot more. I catch alotta greif. Not to mention a few comments of, "WTF is that?!?!" LOL, But thats ok w/me.

I have a few TQ's that cost me pennies vs. a Holley and perform just fine for there application. $20 for the carb, $30 something for a rebuild kit, a can of carb cleaner w/basket to dunk it in. Sheeeeiiiittttttt! Basicly, for $60 a carb, I have 850 cfm of carb that performs real well.

Parts may not be on the shelf for these things like a Holley is at your loal drug store shelf, but it's worth the wait to get them. I have bent up AFB/AVS rods to fit the TQ in order to tune them up. Just bend carefuly and correctly measure twice so you only bend once.
