Hello Harleynut, I was in your shoes years ago. I had rebuilt a couple of Zeniths and they never ran as good as the after market carb. Then, I saw Steve Pargeter's rebuild manual on the Zenith carb. The key was flow testing the jets. If you don't, you have no idea what is going on in your carb. I found that the original jets were just as bad as the repro jets. After flow testiing, you won't believe how great that Zenith carb can be. Ed
