Throttle shaft screws

Post by Farmallgray »

Having brain fade here. What size are the carb throttle shaft screws? I'm thinking 4-40 but I want to make sure.
See my IH, Cub Cadet and tractor pulling youtube videos;

Todd, they are 3-48 x 1/4".
McMaster- Carr has them in brass or stainless.
I'd go with the brass ones and here's a good reason why

If a stainless one ever got loose it would cause all kinds of Hell inside :(

I'll be installing these myself in the not too distant future; is blue loctite a good idea...?
