Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

Right. When you are adjusting the air/fuel mixture screws you are adding or reducing the amount of air/fuel the engine gets.

When you change the idle feed restriction or the idle air bleed (or both) you are changing the air/fuel ratio the engine gets.

Makes sense.

I ordered a 50 pack of set screws from McMaster. Really just going to use those to block off the middle ports for now as I don’t have the drill bits and don’t have the funds for them right now lol, maybe by the end of the weekend I can order them.

I’m assuming in the future if I wanted to tune the emulsion more I would drill out the current holes that are in there and put in set screws and use those as the port hole?
