Check your jets on rebuilt carbs

[TinCup]

I have spoken to a couple of online vendors about certifying the carb jets. My suggestion was to offer guaranteed flow tested jets as a way to validate the quality of their parts versus the hit and miss we get with what is being offered today. Both vendors remarked that they only have one supplier for the jets. I check every jet before I install one today but I would be happy to pay a little more for a set of jets I didn't have to work over.

I thougtht I read on Fordbarn about a guy that sells flow tested jets?

Today I installed my spare Zenith on Henrietta ('29 special coupe) which I rebuilt using flow-tested jets I bought from Renner's Corner:

Once I got the float valve adjusted properly, she ran better than I've ever had her running! I'll probably buy another set for my other Zenith. The jets came with data indicating their actual flow rates (cc/min).

Incidentally, if you don't have Tom Endy's dissertation on rebuilding the Zenith carb, you can find it here:

Dave Gerold also has a paper on performance-testing the Zenith carb:
