Just got the rebuild kit for my Carter YF964S (thanks Carbking ) and was taking a closer look at the carb.

At the throttle shaft, there's a lever linked to the choke that moves with it and that the idle speed screw rests on. It has a tab (red arrow on the attached pic).that doesn't contact the carb body when the choke is full open - should it? If so it would require bending the link rod to keep the choke at full open. Is that something I should mess with or just leave as-is?

Also, there's a special screw (really flat head - yellow arrow in the pic) that wasn't attached to anything, but is just flopping around. What would it's function be and should I just put a nut on it to keep it secure? It looks like someone has cut it short with a hacksaw. Was it supposed to be longer and attach to anything?

Thanks for any thoughts on these things.

The tab in question should contact the throttle body when the choke is wide open. Adjust by bending the choke link.

The screw in question MIGHT have been used to attach a bracket by some previous owner to adapt this unit to something other than its intended purpose.

Glad you liked the kit.

Here is a picture of one off the net ,looks like the threaded piece is a add on fix.

Thanks guys. I'll unscrew the idle adjustment screw to get that extra screw out of there. That's all that's holding it in place. And I'll bend the rod to adjust the lever.

Taking the carb along with me over Christmas to do the rebuild so I can use my son-in-law's ultrasonic cleaner.

I knew I could count on you guys for answers.

I used a friend's ultrasonic cleaner on some random parts, too. Those are really cool.

Got that extra screw out. Obviously someone's poorly thought out solution to some unknown problem.
