thanks everyone who has helped me.
i got to drive my project for the first time today.
what great power.

only thing erking me is high idle.
i have RB header holley(large streetport setup-new)
holley blue fuel pump(set @ 5.5psi)

idle control screw is loose(all the way out)
if i push the throttle lever(on the carb) all the way in, it will idle around 800
as soon as i push the pedal, it will settle around 2k

any ideas?

 

if i retard timing, idle lowers(obviously) but i lose power and
get a stumble from start.

 

i think your fuel pressure is too high also i assume you have a throttle return spring installed?

 

now i have 2 throttle return springs...
the one from racing beat
and the one off my nikki.

seems to help a good bit.

think 5.5psi is too high?

 

according to racing beat, both vacuum inlets to dizzy should be plugged
(aka no vac advance)
sound right to you guys?

 

vacuum bung on carb came plugged...

 

usually high idle is to compensate a vacuum leak. but i'm not sure how your engine would work with the "large streetport"

 

Stock Nikki carb takes 2.5-3.5 psi of fuel. Start at the lower end of the range.

 

that holley needs 6psi.
