I'm cleaning a cb750f ('75) that I picked up. It was sitting in a garage and the guy was moving....so fire sale!!! woo hoo!
but the throttle wouldn't turn, the carb wouldn't budge. I pulled the carbs.. the throttle turns fine..the linkage that is.
So i'm full into the teardown ( still new to this .....but always having mad fun at it)... the bowls had varnish.. but also...moss..yep green moss.. LOL

So I followed the previous instructions and pulled the bowls, jets, etc.. but I couldnt pull the air screw? cause it looks like this.. just turns 360 max.

I think I found out what it was sticking.. #3 appears to be the one bugger.. I found this... what the hell happend here do you think?

heres what the other three look like.
