So I bought the Maxi Frig refrigerant (another thread)
http://67-72chevytrucks.com/vboard/s...d.php?t=765462 And got ready to install some and found this Idler pulley bearing completely obliterated, So I ordered one for $7 and went to work on installing the fuel regulator instead. I lowered the pressure down to 4.5 psi and it runs a million times better. Idles nice and accelerates fabulous. The right side needle still does nothing. I am leaning toward a float issue on that side. I also loosened the covers on the needles to see if they were moving up and down and they go down fine when accelerating. I will try to readjust the float and that is all I will do before this baby gets a Holley. I will check for vacuum leaks at the base when I remove it to adjust the float.I also have a nice one inch Phenolic spacer I may put on as the linkage is way close to the valve cover right now and is a pain to mess with. Did these cars ever have the motor mount issue our trucks have? It has a non cable type linkage on the carb I may swap out for a cable.
