I have that same yellow screwdriver. It’s a decent one.

Looks like it still needs a good cleaning. Even a speck of dirt can easily plug the jets up. Maybe soak it in a bucket of Berryman’s along with a scrub and rinse before reassembly.

I love carburetors.

I used to really not like working on carburetors, you get fuel all over your hands, and they seem so delicate. Took me years to get reasonably good at it.

It is very nice when your engine runs so much better, though.
