[Public-List] A-4 Zenith carb parts (early/cast carb)

Hi Rachel

Funny timing on your question;  I just rebuilt the Zenith carburetor on my old graymarine this week, and after some searching through various sources found a carb kit for it from Car Quest (auto parts store) for the sum of $38.00 CDN.  I don't have the model numbers on me, but I will look them up for you and post them later.  If Car Quest doesn't work out for you (are there car Quests in the States?) you could try a farm equipment parts store -- I believe it's the same carb used back in the day on many models of tractors.   NAPA had nothing (or at least couldn't find anything -- you may have better luck.)

Hello list,

Backround info:

In starting/running my engine for the first time, I found that the (early/cast) carburetor has some issues.  I think that either the main jet is clogged or the float/seat are the source of the problem.

Here is a bit more about the issues:

First of all, the fuel is clean and new.  The boat has a brand new Moyer electric fuel pump system, and it is pumping fuel just fine.  There is fuel getting to the carb (past the pump).

The starter is strong and happy.

The engine runs fine on starter fluid, but will not run or catch at all without it.  This is why I think something is going on in the carburetor.

Another (possibly related or possibly separate problem) is that fuel very slowly drips out the end of the adjustable main jet handle (looks like a radiator stop cock, for reference).

I believe that I should remove the cab and clean or rebuild it. (I'm not sure if cleaning is enough.)

Real question:

As far as buying parts, although I've bought many things from Moyer Marine, and like them as a vendor, the $98 rebuild kit does leave me gasping a bit.  Are these parts available from other sources?  Or should I just get the kit.

I believe I already have the gaskets (PO has about four of every gasket for the boat in a tidy box), but of course they come with the kit if I buy that.

Thanks, and please let me know if you need more information.
