    454 spits out carb at 20% or so throttle at low speed

    so there is a little carbon on the piston but not much. and the distributor seems to be in great shape. it also seems to vary in rpm when i'm cruising like 50rpm i notice a 1-2mph change. maybe its a vacuum leak somewhere? I'll spray around with some carb cleaner today and see if i can find any...

    454 spits out carb at 20% or so throttle at low speed

    I'm a newb so things like this are bound to happen. I would just rather learn how to fix things myself. Even if it requires me to screw some things up.

    454 spits out carb at 20% or so throttle at low speed

    out of the carb not the exhaust. and sometimes it diesels when i turn it off. not so much after the rebuild. i'll have a chance to work on the truck this afternoon and i'll post the results. it sounds like a pop not really loud but it kills the engine for a split second and it continues to run.

    454 spits out carb at 20% or so throttle at low speed

    At take off at about 20% throttle it seems to bog a little then spit out the carb. If I blip the throttle it'll get better and take off. Seems like its lean. Never has this issue when I get on it with more throttle. Where should I make this adjustment? Air fuel screws on the front of the...
