I am rebuilding two Model B carburetors. I ordered two rebuild kits. They are labeled 00511-1 Sacramento Vintage Ford. I flow tested the jets and the results were not what I thought they should have been. I used a 37 1/4" head.
For the Idle jets I recorded 58 and 60.
For the Main jets I recorded 80 for one and 83 for the other.
For the Cap Jet I got 378 and 376.
For the Comp jet I got 148 and 142.
For the Power jet I got 46 and 44.
The Main and Power jets are way off. I know how to adjust the jets by drilling. My questions are ---> Has anyone else measured the flow rates for the jets in the 00511-1 B cab rebuild kit? If so what flow rates did you measure and did you open up the jets? Or has anyone rebuilt a B carb with this kit without adjusting the jets? If so did the engine run lean with not enough power?
Below is a table from Vince Falter's "Ford Garage" showing flow rates from various sources.
