thread locker - carb throttle/choke screws

[bkahler]

On the Carter B&B carburetors the choke and throttle plates are held in place by 3/48 brass screws that are notched on the ends and then spread so they won't back out.

I've found replacement brass screws from the local hardware store obviously without the notches but I'm wondering if some kind of loctite thread locker would work just as well?

Any thoughts or suggestions?

Thanks!

being brass..a slight tap with a center punch bottom center should be enough to distort the thread but yet allow them to be removed at a later date..method two is if protruding a tad more than a thread or so...slot and spread..

Loctite would keep them in there alright,but being brass, ever getting them out again could be a problem as you would probably ruin the heads before they would turn.

I didn't think thread locker held things that tight. I thought it was more for vibration type environments.

The green locktite would be used for these little screws and it is thin enough you would apply it after making up the connection. Yes, it will flow into the threads and will hold them tight. Drawbacks? You will need to heat them up pretty good to get the locktite to let go.

I did not secure my brass screws enough. After a while they let go and the plate fell down and was partially blocking the exhaust pipe gases. So right now I am running with no plate. When I make the repair I will dimple the threads heavily or groove and spread the screw ends to insure they never loosen. I can always grind or file the distorted threads away in the future and the little screws are cheap. The factory method lasted 50 years, right?
