Carb tuning, larger accelerator pump nozzle?

Here are some pics of mine and main body. This is on the primary side. I have not removed the secondary side. Sorry it was still shiny from fuel.

Well beat me with a broom and call me Sally. I’d pin those emulsion holes and see what they are. You need to block off the middle one.

Also I can see the idle feed restrictor is at the top. It needs to be moved down to the lower hole. You’ll need some 6-32 x 3/16 brass set screws, a 6-32 tap, a 80-61 drill set and a pin vise so you can drill and tap what you need.

EDIT: my bad. TJ noticed and I didn’t that the emulsion is already tapped. So you can buy blanks and drill them to size or buy those already drilled. I don’t think you can do that for the idle feed restriction. You’ll need to tap those.
