Ok, so my poor Mustang failed inspection due to horrendous exhaust leak (84 decibels in cabin). I got it back from my mechanic with a new exhaust and it started a bit rough. I tried to find information on tuning the carb (Holley 1946) or making adjustment at least and couldn't find a dumbed down enough version. I hope one of you (guardian angels) has some experience with the Holley 1946.
There is a screw on the side which I understand is the idle adjustment. If I turn it too much the car will choke out. I played with it for a bit and if the car will start it will idle nicely. (Or at least nicer)
There is a large flat head screw looking piece on the front I think this is the choke. This is where my questions begin. I understand that as the weather changed I will need to play around with the choke. For instance:
The carb hasn't been adjusted since the beginning of winter. and was starting rough or not at all. Yesterday I closed the choke a bit (about an 8th turn) and the car started right up (85 degrees outside) and ran beautifully. This morning (about 20 degrees cooler outside, 65) the car wouldn't start.
So, when the weather is warmer do I want to choke closed more or open more?
How often should I adjust the idle?
How often should I adjust the choke?
Any information or advice is appreciated!
