Hi again,

This is more of an FYI for others looking for this info.

Finally got somewhere.  Following Walt’s advice above, I had to remove the carb to see anything at all, and once I got the grime off I could see that it was a Tryton.

Typing this name into Google eventually got me to TSracing and their parts catalog, where I learned that there are two different versions of this engine.  A 125cc and a 118cc.  The first one has a TX designation and the smaller one is called a VX.  They have different gaskets for the reed-valve to block and the reed-valve to carb connections.

Here is how to tell what you got:

Look on the front of the engine, lower side near where the engine mount is, and you should find a number.  If that number is above 1000 it’s a TX125.  If the number is below 1000 it’s a VX118.

You can also look at the top of the crank case near the reed valve opening there may be a letter “T” stamped in the case.  This means you got a TX125.

I found the T and it looks like this:

(Well, it would look like this if I could get the picture posted.  But I can’t, so you’ll just have to imagine.)

Hope this helps somebody else looking for this.

Hi Taylor, and thanks for the info.  I’m not aware of which of the crank pins I have, but I’ll probably have TSRacing take a look at the whole kart eventually.

I finally got the parts and the carb rebuilt.  Took me a while to figure out how to set the needle arm so that it could not leak fuel all over my floor.  However, it still will not start.  I got a spark, but no fuel.  I got a slight fuel drip out of the front of the carb after cranking, but nothing gets into the cylinder, the spark plug is dry.  So more research ahead.

Thanks again for your info, it all adds to my knowledge.
