Re: Zenith 2405N replacement carburetor
The following dimensions show why the 2405N should give better performance than the Zenith-1 and Zenith 2.
Diameter at Choke location: (Throttle locations have similar differences).
Zenith 1 and 2: 1.536 in.
Zenith 2405N: 1.860 in.
The Zenith B-1 and B-2 dimensions are similar to those of the 2405N.
The B-1. B-2, and 2405N have Power Jets according to an old Table that I made. I don't know how the Power Jet works in the 2405N.
