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

Got the carb reset as well as my new cable and bracket. Painfully I had to cut the bracket as the part for the springs was hitting the AC compressor lol.

With the t slot at a square, and about 16 degrees initial timing it idles at a little over 600. Probably fine for this motor as my AC doesn’t work so it won’t be pulling any power, probably will just need a kick up module for when the compressor is running.

I think the hesitation is from the transmission actually instead of the carb, unless you wouldn’t notice vacuum spiking when the engine lean surges. I recall it did the same thing with the v6 on efi, but how a manual transmission is slipping at a cruise with the clutch fully engaged is beyond me. I don’t smell clutch.

This is probably a stupid question though, so I have the timing up quite a bit running premium, so when the vacuum advance is all in it’s got a lot of timing, would that cause burbling out of the exhaust? I always thought that was retarding the timing. I can hear it when I’m decelerating with my foot barely on the throttle, so it’s cracked open. Fully off no burbles, only decel with cracked throttle


You need to control when the vacuum advance starts and then how much advance it adds.

You have to test for it. It’s damn hard to do in the car.

I suggest @halifaxhops. Send him your distributor and let him tune it for you.

Well worth the money.
