So I just finished installing the carb. When I was getting the fuel line in I pushed down on these and now they move as if on a spring. Before the rebuild they seemed locked open and wouldn't move if pushed on now I can push them closed. I took the carb back off and looked for something to be broken but everything seemed fine. Does anyone know should these open and close with your finger or should they locked open? The boat started in the drive way and run as good as ever. What do you guys think?
PS you guys were right the carb rebuild was pretty easy, thanks for all your help so far.

Choke plate. It is operated by the electric choke that is attached to the carb. It has a specific setting that allows the choke to work in the manner intended. .

From their site of technical documents showing the correct settings and responses.

. Cloaked is correct. That thing is the choke plate and is fully closed for a cold start. The round black thing on the side of the carb is the electric choke(spring). After you start the engine, the choke(spring) heats up by 12V and gradually opens the choke. If you want to see it operate., turn the key to on with a cold engine and watch it gradually open as the electric choke heats up, has nothing to do with the temp of the engine.

Thanks but that doesn't tell me what I need to know. I have the choke hooked up and didn't adjust it. I am wondering if those butterflies should seem locked open or if they should move as if on a spring. I am wonder if when I was pushing on it to get the fuel line in (which I didn't realize I was doing and shouldn't have done) I striped something inside the choke and now I need to replace that. I am hoping someone can walk out to there and see if they move freely or not.

It will move with a push of a fingertip. It's not hurt. However You need to have the choke setting adjusted properly for the choke to do it's thing. Read the link I posted.

So it shouldn't have been stuck open, should it seem to move freely as if on a spring? It was open when I took it off the boat and never moved. I will let it cool and go back out and look at it. It should be closed when I go back to look when it's cold?

Thanks. I have read through the holley pdf you sent. I am hoping it's going to be OK. I didn't move the choke adjustment during the rebuild (it was a limited rebuild only what was necessary) I am hoping it was just gummed up with some residue and now is moving correctly.

When the boat is warmed up and I am driving around should they be fully open or closed?

Thanks for all your help and the quick reply.

Your choke plate should be open under normal operating temperature. A rebuild can affect the choke position if indeed a gasket was leaking, etc.

Patience. The 4160 is a decent carb once you mess with it a bit.

Thanks everyone for all the advice and help. Rebuilding the carb wasn't that hard at all. I took the boat out today and it ran like a champ.
Wanted to let you everything worked out. I haven't done the control cable let. I need to figure out what length and order it.

Great to hear the rebuild went well. It's especially rewarding when it all works like it is supposed to. Job well done
