Carb Conversion to Weber 45 MCHH

Today I replaced the stock ZS carb with a Weber 45 MCHH side draft. The new carb should run better, be easier to tune and give a little more power.

Here is a pic of the ZS carb with the tubes labeled and the filter off.

I still need to deal with the vacuum hoses and tune the carb a little, but it seems to run great.

Here is a link to where you can get a carb like this..

The Carb is the stock Zenith Stromberg. Its not that great, it runs rich and needs rebuilding. Rather than do that I decided to order the Weber 45 MCHH that bolts on to the existing manifold. From what I have read this is a pretty simple mod, although it is possible that the air filter will run into the brake cylinder. Apparently there is an adapter that can take of that. We'll just have to wait and see.
Heres a pic of the kit and a link to it.

It should be in tomorrow, although in the meantime we have another project.
