I did the bowl mod on my weber and it still floods out on easy trails. As cheesy said, you have to make frequent adjustments to webers for where you're driving. I am tired of adjusting at home and re-adjusting for altitude/weather as I drove. Pointless waste of time. Carefully rebuild a factory card and call it good, and get the adapter to run the 22r carb if you have a 20r intake manifold (what I'm doing).
Or better yet, swap it out for propane or efi.
