Thanks cletis - it is a gmc engine. I honestly had no clue they didn't just use Chevy engines. So, is it a 235? (I thought I saw 236 as the engine for this model, thought just a typo/estimate type of thing) I think you know what's going on, so.. why then, does this metal plunger have a slot in it so that rod can slide in and lock into it? Wouldn't that defeat the purpose?
The rest of the carb, except for the throttle body, is in surprisingly good shape. The throttle body was rusted terribly, inside the bushings, and even the flat piece of metal that turns was rusted to the walls of the throttle body. (I know a good bit about carbs, but don't know the name of that part...)
Anyway, thanks for the help and thanks for any more. You guys are great!
