Idle problem on C15 261 CU IN

[TCLARK]

Hi Bob
The vacuum reading was about 6 at 500 rpm. It went up to 18 at 1000 rpm.
The vacuum held steady at both rpms so that is good. I took it out for a run
and it ran so nice I m almost afraid to touch it. I set the idle jet to 1 3/4 turns
as per factory spec (Chiltons). I will go out and play with the idle screww at 800 and then at 700 and see if I can fine tune. This morn I barely touched the starter and she fired up instantly; never done that before. This is the pertronix and the big spark plug gap doing its thing. I may also get the ether out, some guys use acetylene as a final leak check

Hi Lynn
I did check the manifold and all looks good, I am using noncopper leads
from a hot rod shop they were expensive but leakproof as the wires are so close to the firewall . My coil is a Baster II 8802 I have it powered through the 12-8 volt resistor. I was wondering with pertronix if I need that resister
or maybe its a coil spec?

Thanks everybody for the help and excellent advice . Merry Christmas to all!!
Cheers Terry
