Carb queery's

Moper; I did just that with no luck. Below is a copy and paste reply to someone else on the topic. Read on;

This is what I was thinking since it is a stock long block 318 with the above mentioned. I was thinking the throttle bore may not be small enuff to make use of the vacuum signal. Which by the way is 15 inch on the auto meter gauge. (I was in a rush last night and hooked it to the carbs front ports (Both small ones) and found zip.

I attached it to the rear of the current big AVS and got a decent reading.

I started with a small AVS of a 340. Exact numbers can be given, just do not remember them now. The problem there was no idle circuit gas. I could get it down to a 1,000 rpm. But it was in the main metering. I used compresed air on all the holes in the carb. ...(Moper, And all the carbs tried. small AVS, big AVS, Carter AFB 750 cfm.)

Before I re-swap on the smaller carb and live with it....for now....I'm going to get into the carb again and richin it up since a low signal will be a pain to tune anything, the riching might help. I may have gone to far in setting up the carb only looking at the idle side of it. (Moper, not sure if this is the right direction?)

I mostly have good luck with the OE Carters. Never a problem with to big because they were never around to use. Allways the small ones were in house.

I'll be back tomorrow (I think) with another report and try. Whatchin the lil'guy now. HIs B-day presents are in the garage and I do not want him to see them if I start working on the car.
