Thrust issues with AFR gauge and Brawler carb

All numbers are what I have personally measured. Except cam degrees.

Ok, so what size are the emulsion holes?

If you are just watching an AFR gauge and not data logging you won’t see the negative affects of too many emulsion holes open or too big of holes or both.

You will never see it on a gauge because the resolution won’t show it but what you end up with is (this would be looking at your AFR on a graph) you will see the line saw tooth all the time.

What that means is you can have your AFR could be (I’m making up numbers here but the result is the same) as high as 14:1 and as low as 12:1 in a short (relatively speaking) dyno pull.

We know from data logging in a car the exact same thing happens.

I used those numbers because I have personally seen it that bad.

Also, just so I’m clear did you use pin gauges or drill bits to check the sizes or are you going off the papers that came with it?
