How to adjust choke pull-off on Holley style Summit carb?

[JFetter]

I have a Summit SUM-M08600VS that is acting up. Quite often when starting, it will not start at all. (unless I depress the pedal and hold it that way)

I suspect it is flooding, and think that it's due to lack of air.

Here's my carb:

I've read that it's just a holley knockoff.


I have reset the electric choke housing to the 'factory' condition (index marker), but as I understand it, this shouldn't matter anyway. This is a problem during initial startup.

Some old holley guides talk about using a bent paper clip to adjust the "Choke Qualifying adjustment", but I don't think that applies to my carb?? Pic attached.



I'm suspecting vacuum leak or adjustment problem.

Am I on the right track here?

Is there an easy way to check the choke pull-off operation without the engine running? I.E pulling off one of the vacuum hoses and attaching to a vacuum tool?

I'm very new to carbs and sort of learning on my own here.

Thanks!

When you finally get it running, where is the level of the gas in the site glass?

[JFetter]

About 1/2 full.

Lower the fuel level to 1/4 of the sight glass on both bowls. Might stop your flooding and starting problem.

Ok thanks! I'll give that a try.
