How To Measure Fuel Volume.

This is not your whole problem. But I've run those carbs before and those jet sizes are a few sizes bigger than I ever ran. Especially in the front. As some said earlier the you need to check the AFR a chassis dyno is great for that. Or you could install a wide band O2 and and watch it yourself. I had one of those carbs and without a power valve in the rear it mostly ran the quickest and fastest with 70 in the front and 78 in the back. On pump gas and 68 & 76 on race gas. Good luck with your project.
