The Zenith on my '29 roadster has been gone through by a much recommended rebuilder I met here on the ..'Barn. After his "magic"
the car ran a whole lot better. However, if I try and run with the gav
less then 1/2 open. The car will backfire every now and then when I let
off the gas like during shifting. No idea what my mpg is. I just add non-ethanol gas and some marvel mystery oil when needed. I've got a B-W
OD to, so I'm sure that it helps with the mileage.
