I started working on the carburetors yesterday to prepare for installing them. I rebuild them around a year ago, and they have been sitting on a shelf while the engine work was being completed. So I put them in a vise, and got them leveled. After putting the clear tubes on For the float level test I started to add fuel. Okay, dumbass, maybe you should make sure the float bowl screws are tightened... :dry: Once I got my act together, I didn't have fuel running all over my bench! I had good (or close) levels on carbs 1, 2, and 3, but #4 wasn't showing any fuel at all. So I drained them all and took all the float bowls off. It looks like the new float needle was sticking in the seat. I got it free, reassembled everything, and the same thing happened - no fuel getting to the #4 carb. Today I will pull it all apart again to see if it's a stuck needle again (will get it cleaned out with carb cleaner, but it was all clean and dry when it was rebuilt?) or if there is a blockage between the 3 and 4 carb fuel passage. Hopefully I can get this straightened out without having to ungang the carbs, but I will figure it out... Since I had the fuel flow issue on #4 I didn't take any actual measurements on the fuel levels of the other three, but visually they were very close to the same amount of distance just below the top of the float bowls. Measurements will be taken as soon as I have fuel flowing to all of them.

A while back I had some valve shims go missing in the USPS system. They shipped from Costa Mesa, CA on Dec. 14, 2020. I finally received them today! Don't need them any longer, but they will be good for the first valve adjustment after break in and some miles. I will always pay a little more for UPS or Fed-X. Sheesh!
