Title: Solex Swap out
Post by: Shalka04 on December 07, 2012, 08:08:50 PM

I just picked up a master rebuild kit for my Carter WO, so no mystery how i'll be spending my free time this winter.
However so I could keep my rig on the road I picked up a Solex carb to swap in while working on the Carter.
Who ever said they are direct swaps is a fool.
If any one has any photos on how the linkage hooks up or works out that would be appreciated.
Also any info on connecting the fuel side?
I'm worried / curious about the banjo bolt on the solex being metric or something as a 1/4 reducer only thresd in maybe two or three flights.

Any help would be appreciated.

Here you go! �if I remember right, you need a 5/16 inverted flare to 1/4 inverted flare adapter to hook up the fuel line and longer cables for the hand throttle and choke. I have a replacement wo setting on the fender as soon as get a chance to rebuild it and my solex can go on the shelf. Hope this helps!!

GMCJR, Thanks for the info and the MUCH needed photos.
I've discovered that the fitting on the Solex is infact metric, BUT that the 5/16th fitting is so close that it will work as long as it goes in with a little love and care.
In the morning i'm out to do more investigation.  Idealy I'd love to find a ??Metric to 1/4 adapter but out here in the desert hopes for that aren't high.  I'm also wondering about replacing the banjo with one that's standard thread.  I need a rigid solution regardless as i'm going to hang a Carter sediment filter right off the carb, so a barbed fitting with some hose just won't cut it.

Hi John.

After a recent Carter WO rebuild, I was able to replace my Solex.  You may be surprised how straight forward the Carter bebuild is.  I am no pro.  It took me a couple days worth of free time to do it.  

I will admit, I was nervous about it, but was encouraged by members of this page to give it a go.  One of the better decisions I've made.  I followed this direction:

You may find that the efforts you are putting into the Solex could be better spent on your Carter.  With the Solex, in addition to working out the fuel connections and the linkage connections, you will need to add a fuel pressure regulator somewhere between the fuel pump and the Solex.  The fuel pressure must be toned down for the Solex to perform well.
