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

I have this one for the small sizes. Shows number and measured size for each from 1-60. I’d also recommend getting a number zero or number one center drill to start the holes so the drill doesn’t wander and drill straight without breaking. Just need to use the center drill to put a dimple in the brass that the drill can use as a guide to get started. There can be a trick to drilling small holes. You need to be patient and pet drill clearing the flute often.

Awesome, thanks for the link I’ll take a look soon. Just got home after a strange ordeal.

I started to smell gas so I pulled over at a gas station conveniently and right as I rolled into the lit up area the engine died. Popped the hood, took off the air cleaner and the primary side of the carb was literally flooded with gas up to the boosters.

No idea why that happened, maybe it blew a seal on the bowl? But regardless I messed around with it, checked fuel pressure and it’s right at 6.5-7psi. Though once I started driving again after blowing all the gas out the spark plugs I noticed my volt meter bouncing around like crazy and at the high end it was beyond where it normally is (and this alternator/regulator combo is a “happy” one so to speak, it runs high). So maybe the regulator or alternator is going bad, caused high voltage to the pump, and the pressure burst the float?

Need to take a look tomorrow when I have daylight. Going to measure the voltage and what not. Right now as a bandaid I have the float screw all the way in and it’s just above halfway on the sight glass. Though it’s weird the secondary side was perfectly fine.
