KB Carb identification HELP
Long story short, my father and I bought a team out and we sold off the cars as we had you own, and kept the parts, lift, tire machine, engine parts… well recently my father was diagnosed with pancreatic cancer, and passed away just 26 days later.. well here I am now, somewhat lost as we had a deal, I make it turn and get the power to the ground, and well, he makes the power (he was a engine builder by trade) I’ve learned a significant amount of engine tuning being around it and asking questions but we owned 3 carbs that were our 1-2-3 go to’s but I found a KB in a carb box that I forgot we had (I think he might have too) but it’s in perfect condition, but only has a few markings on it, any help with identification would be super as one skill I lack is where and what to measure to identify the carb.
Stamped into it was
1.590 GAS and above that was 20041
and in another spot
5207 and KB4150HP
