How do you adjust the pull off on a holley electric choke? The vacum pull off is integrated into the electric choke housing but there doesn't seem to be a way to adjust. I have cold running problems untill warm up (because I have to lean the choke adjustment because of the pull off not opening enough).

Thanks

there should be a hairpin style loop in the link. pinch it together a little to increase amount of choke pull-off.

you will probably still have to lean the choke way out though. Truth is, the Holley electric choke heater is a POS and always has been. it doesn't get hot enough soon enough. It's been like that since I can remeber, back in the mid-70's.

No hairpin loop in the link. There is a slight bend to it but it doesn't look like it's there for adjustment. I suppose I could bend it but it would be an R&R of the assy each time because it's not the kine of unit I can apply a vacum pump to.

There is a screw ( like a set screw) that goes into the vacum piston assy. Is this an adjusting screw?

I don't know why Holley "hides" this info. It's not even included with the electric choke kits!

You're looking for Page 4, figure 15--and also glance at figure 9, page 3. Figure 9 doesn't exactly apply but shows the relationship of the choke blade/air horn, and how to measure the gap.

You'll need a "special tool"--a paper clip with the end bent at a 90* angle.

Also note that you'll want to align the fast idle linkage so that the fast idle cam drops to the second-highest highest step when the choke pulloff pops the choke blade off.

This forum ROCKS!!!!

I couldn't find that data anywhere on holley's website.

Thanks!
