Reply To: Resizing UU-2 main jets

Thank you for the useful information Karl, I appreciate it.

I spent a half hour on the phone with John at The Carburetor Shop and he went through the books with me to verify that my carburetor was right internally, he also sold me some literature I probably didn’t need but after being that helpful I didn’t mind.

The carburetor that was on my car is basically a factory setup for the 30 model which is a very similar engine and it seems that drilling the jets up should yield better results. Don’t know if 30 had the large air horn but this one does and lined up perfectly with the air cleaner and inlet tube connected to the engine pan.

I’ll still contact Arnold as it will be a while before I need it complete again, I plan on looking at the valves and cooling system plus anything else that jumps out while I have the head & oil pan off.
