Any Holley experts out there?
My carburetor started giving me trouble today. Again. It's a Holley
4150 (600 CFM 4 barrel) on an '85 CJ-7 with an AMC 360. It wants to
close the choke every time I give it some gas. This makes it idle
about 1800 rpm. I have to push the fast idle cam (little red plastic
thing) down to get it to unchoke and idle normally. But then, when I
give it a little gas again, it chokes again. It normally idles lower
than that when cold, maybe 1200 - 1400 rpm, and a heck of a lot lower
once warm, about 600 rpm. I took the choke parts off just to see if
there was anything obviously broken - didn't see anything. The spring
is OK. The connections seem OK (electric choke). It was set to the
fifth mark from the right. I moved it to the fourth, but by then it
was dinner time. I'll ride it around tomorrow and see it anything I
did made any difference. If anyone has any ideas, I could use some
help. I don't have much experience with carbs.
Thanks.

Re: Any Holley experts out there?
That's a nice carburetor:
http://www.rockcrawler.com/techrepor...70_box_550.jpg
If the RPM had increased before you took it a part I would look for a
vacuum leak. If after, then you have not put the heat sensitive spring
back the lever fork lever, for sure it's now too far towards the rich
side, just twist it back CC if you can't find the fault. In the sixties
it would have had a choke pull off that would have look like this:
http://esc04.midphase.com/~chevesd//15_15.JPG that would have been the
problem.

Thanks LW (Bill) for the response.
This post is for posterity - in case someone has a similar problem and
searches here for help. It was really pretty simple. I got some great
help from the Holley web site. <www.Holley.com> They have an online
technical help section <carburetor@holley.com> that steered me in the
right direction. I told him what was happening, he told me exactly
what to check and he was exactly right. The resistor spring in the
choke cap must have a 12V power supply to work correctly. The current
flow helps heat the metallic spring to more quickly re-open the choke.
My power lead had broken somewhere back in the harness. My spring
wasn't getting warm enough to de-choke. Luckily nothing else has lost
power (yet) so it seems to be just the lead to the choke. I simply
connected it to another switched power supply and voila! It works! The
Magnificent-7 motors on! And I learned a thing or two about
carburetors & chokes in the process.

Thanks LW (Bill) for the response.
This post is for posterity - in case someone has a similar problem and
searches here for help. It was really pretty simple. I got some great
help from the Holley web site. <www.Holley.com> They have an online
technical help section <carburetor@holley.com> that steered me in the
right direction. I told him what was happening, he told me exactly
what to check and he was exactly right. The resistor spring in the
choke cap must have a 12V power supply to work correctly. The current
flow helps heat the metallic spring to more quickly re-open the choke.
My power lead had broken somewhere back in the harness. My spring
wasn't getting warm enough to de-choke. Luckily nothing else has lost
power (yet) so it seems to be just the lead to the choke. I simply
connected it to another switched power supply and voila! It works! The
Magnificent-7 motors on! And I learned a thing or two about
carburetors & chokes in the process.
