I picked up a Carter Model N 655 on eBay. As I was cleaning it up I wondered if I could convert this to a Model N 703 by replacing the Brass Main Nozzle and adding a new High Speed Main Fuel Needle Adjuster made for the Model N 703.
I looked it over and it looks exactly like my Carter Model N 703, except for the fixed High Speed adjustment. I don't know if the Model N 655 was ever used on a J engine like mine or if it was only used on an H engine.
Does anyone have any experience with this? I was wonder if it would be better to leave it as a Model N 655 or it would be more saleable if it were a Model N 703. I can only image that the 655 evolved to the 703 for a good reason but I don't know what vintage Whizzer people are looking for.
Perhaps someone with the knowledge could post some additional information.
Below I have provided some pictures:
I have no idea why it needs a Welch Plug but I guess that when gas freezes that it expands.
The Throttle is in good shape and I hear that a throttle shaft bushing can be added to make the seal perfect.
The actual Number is not easy to see, before I cleaned it up I wasn't sure what I had.
The cast aluminum housing is identical to by Model N 703
The brass bowl is in great shape, you can't see it but the bowl nut is threaded into an internal part that has all its threads (no striped threads)
I understand that all Whizzer Carter Model N's had a fuel inlet from the top and not from the side.
You can see the Fixed high speed screw on the top
This shows the Choke plate with spring and ball detent still intact.
There is a small dent in the Brass bowl, but overall its in good shape.
