Holley 1850-5

What's your AVS doing or not doing
Actually I now think the carb is fine. I just went through the motor, 20 over KB pistons ,Same crank, same cam, Eddy heads 60175, Motor sounds good at idle but acts like a severe vacuum leak or like timing marks are off. Stalls , won't accelerate properly. I know I aligned it correctly for stock setting. Timing is at 8 BTC 35' Total. Motor was tired but ran good but sat 10 years before rebuild.New Gas tank and stock fuel pump . I have 15 in. of vacuum at idle .Not sure if this is low for stock 1968 4 speed cam but can't recall what it use to run at . Comp to me is little high at 180 . In the process of moving so it's been hard to get to work on it. Have no Mopar mechanic friends to help .
