I'm confused, why did you say this?

The "proper" way to adjust the choke is to set it to 1/16-1/8"open when closed/cold. That ensures that when the bimetallic spring starts to open it, it will have an immediate effect and will open fully..


I've always set then to almost closed and it works.

This whole thing is starting to sound like a discussion of the proper way to wipe your a**

Do I wipe upwards or downwards?

Do I use short strokes or long strokes?

How many times should I wipe?

Should I be standing up or sitting on the pot ?

Do I run the bathroom fan for 30 seconds before doing anything?

How should I fold the toilet paper?

Just like there's more than one way to do "the wipe" , there's more than one way to start the boat

What brand tp is best for older equiptment? How much do I need to use ? I hear some like to keep it original and just use a hand,others use a corn cob. Any special additives? I always use the fan to disperse explosive gasses.

The Choke not closing fully is the problem...I pushed it shut and it fired right up cold. What could be preventing it from closing fully when closed??

Thanks!

Try the adjustment of the bimetallic spring housing when the engine is cold. It's the black cover with the three screws.

You may need a new choke spring. They can wear out. Auto part store should have one.

Chris,
How did you determine the bimetallic spring is the problem? Did you watch the Holley video on adjustment?

Here is how I troubleshot...shooted.

The choke, when cold, was manually moved to the full open position and released. It did not close fully. It seemed like it didn’t have enough “spring force” to close it.

I shut it manually and it fired right up and the cam opened the choke as it warmed.

The next day I looked at it and the cam was returned to the cold position but the choke was not completely closed.

I thought the spring closed the choke, and the cam opened it it up as it warmed. Correspondingly, as it cools the cam move to the cold position and the spring closes the choke manually.

I am working and will watch the video when I get off. I appreciate the help!

Chris,
Do watch the video when you get off work.

The "spring" isn't a true spring but rather a bimetallic spring meaning it's made with two materials that expand at a different rate. When power is applied at start up, the spring warms up and due to the different rates of expansion the spring twists and OPENS the choke.

Look at your other thread on the same subject for some pictures and info.

To put it into easy to understand English the "spring" heats up and unwinds and opens the ckoke when voltage is applied from the ignition system.

When you turn the key to OFF , the voltage is removed and the "spring" cools, winds back up and closes the choke

The fast idle cam mechanism doesn't apply to a marine Holley. Some of the parts are there and some aren't. It's non functional.

The Holley video in the other thread is for an automotive carburetor with a fast idle cam that's functional

In your case a guy named Otto is the fast idle cam. You start it and bump the speed up a little while it warms up

They'll probably want to know

your mother's maiden name

the name of the street you grew up on

also the name of your first pet and of course your social security number and charge card info

Or you could take the heating element ( the black cap) with you and make sure you get one for a marine Holley

Chris,
Is the carb marine? It doesn't make a difference for adjusting the bimetallic choke spring but it may make a difference with your safety.
