Carb Adjustments
Well i have i bbl carb and i wanted to hear it straight the best was to set the thing, i got the truck from my father who fulled with it forever so i know its not right,
I know he screwed with the electric choke spring tighting and loosing and i need to know how to get this back to original or set it right,
I needinfo from start to finish including idle rpm
sometimes the thing shakes, turns off in tight turns or while stoping on a hill,
ill try to get a pic tommorrow to show how the vacume lines are run because he just has a edelbrock air cleaner were is the original had a lot of differnet hoses.

What year is the vehicle? First thing to do is replace all the old vacuum hoses and ensure there are no leaks. My Bronco had a hidden elbow on the bottom of the vacuum tree that drove me nuts until I found and capped it. Then set the timing to 10*.
There are only two screws on the carb, idle speed on the throttle linkage and idle mixture near the base of the carb. Set the idle speed with a tach. Use a vacuum gauge to set the idle mixture - go 1/4 turn at a time up to a full turn in both directions and see where you get the highest vacuum reading. Reset the idle if it changed much, then confirm the timing is still correct.
