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

[crufone at comcast.net]

Rachel, 



Sorry to hear that you sold the A 30.  I will have to agree with James that these cast Zenith Carburetors are not unique to the A-4 or Gray Marine engines.  Gray uses Continental engines which are still in business.  An olde timey auto parts store with a cross reference guide should be able to find the carb kit.  Also do a search on-line for Zenith Carbs.  Many early automobiles and tractors with four cylinder motors used Zenith carbs. 



If you can get the carburetor apart the brass parts can be cleaned of gunk, passages cleared of debris and reassembled to achieve a fine working carburetor. 



These are really simple non-sophisticated devices.  If carb is dripping fuel it will most likely need a new needle and seat assembly, which usually can be purchased separately.

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.
