Radiator hooked to the Carb? (water heated choke)

95Pony · 06-14-2004

We are now taking apart everything to remove the engine and transmission. Can someone tell me what is up with the carburator having radiator fluid or something running through it? Wouldn't that assist with overheating?

I searched first and couldn't find this. Thanks!

That is for the water choke on the carb.When fluid gets hot it shuts the choke off.

Thanks! And does that work well? Wondering if we should rebuild this one or go with an update (Weber)...?

Solex carbs are great for door stops,If you clean them properly.I would go with the weber with an electric choke as I never did like water going through the carb.

LOL. Doorstop it is. I must agree.

yes, get a Weber. And if you lived in a colder climate, I would suggest that the 32/36 DGAV ("A" as in "Aqua", as in water-sensed choke) would be a good choice. It's more sensitive to actual engine temperature, while the DGEV ("E" as in "Electric") simply uses a electric current to open the choke by heating a bi-metallic strip. More time dependent than temperature, but much simpler than the water choke. Which does NOT contribute to overheating.

As Keith stated and others, get the Weber, which type depends on your preference, whether you want the additional heater hoses running to the carb or an electrical wire. Both types are continually active, that is the coolant will continually flow throught the choke housing or you will have current flowing to the electrical heating element in the choke housing. Both systems heat a bi-metallic strip that OPENS the choke plate in the carb. Noting you live in New Mexico, you have fairly hot summers and snow in winter, so you can use either choke setup and both will do the job. But do a search for the correct jetting of the weber, there is a lot that can be done to it to really get the most out of your car. HTH.
