The Stovebolt Site Forums The Shop Area Engine Shop Tired of my YF

My 41 suburban did run like a top. It has a YF carter that is not working right even after a rebuild. I have many other truck of the same era with W1 carters that run flawless. I would like to use a w1 but the bolt spacing is different for the manifold. Do any w1 have a wide bolt flange or is a w2 an option?

Steve - what are your symptoms? Possibly there is a different issue.

Carter DID produce a W-2, but, while technically a production model, as it was used for a few months on the 1931 Nash; it was really an experimental model. Even if you did find one (haven't seen one for sale for years other than from that grumpy old Missouri hillbilly), it has the very early W series technology which had issues. Also, since they are exceptionally scarce, they tend to be fairly pricey. If all of the above has not talked you out of looking for one, call me; but better to figure out why the YF is not performing to your satisfaction.

Hello Jon,

It will idle, but not smooth. No acceleration, seems like a lack of fuel.

No points or condenser. Pertronics equipped. Plugs and wires good. Ran great before winter. Rebuilt carb still runs like crap.

I guess I should pull it apart again?

Steve - before throwing rocks at the carb, try a set of points and a new condenser.

I won't try to talk you out of it permanently, but when having engine issues and a pertronix installed, ALWAYS check that first. Also, upgrade the generator to an alternator if you have not already done do. Generators cannot provide the constant voltage electronics like.

Let us know.

Jon makes a good point about engine problem diagnosis strategy. Always do the carb last unless it is spewing gas everywhere.
They are a chunk of metal with a bunch of holes and a diaphragm and a check ball or two. As simple as they are, it is difficult to open one up and say "Ah ha, there's the trouble". In my experience I am more liable to do more harm than good when digging into the carb. That's why I save it for last. And usually the carb wasn't the problem to begin with.
