Is it possible to put a electronic choke adapter on a 77 Vette . And where can I buy one.


Thanks this is my first time on the forum

In my experience, the only electronic choke thermostats I've seen, are on Holley carbs. You replace the mechanical thermostat with the electric one, and run a power wire to an "ignition on" 12V source.

As leadfoot posted, if your carb is from a 77, the choke spring mechanism can be easily replaced by an electric version for about $25. If the carb is a replacement form a much earlier carb with a divorced choke, it can be converted with a setup that can be purchased on ebay for about $75.

You can purchase one from most auto parts stores. You can also purchase a pigtail wire connector or use a spade connector. The insulator between the existing choke and the housing has to be removed. This is because the choke element grounds to the carburetor.
That being said, I recently did this on my 1979. After making the conversion I switched back to the original spring style. Once the original is adjusted, along with the correct amount of pull off, I found the original style works better. The original opens from heat generated by the engine, where as the electric opens after so many minutes, irregardless of how warm the engine is.

This is the one I have on my 78. The instruction sheet shows what you will need to do & as noted remove the gasket :

When reassembling the unit, do not use the gasket. The gasket will prevent a good electrical connection between the coil and ground.

FWIW...

Most choke problems are due to binding linkages and/or improper adjustment of choke components. If you have such problems and just convert to an electric choke, you will still have problems with it.

Your FIRST order of business is to follow instructions in the Chevrolet Chassis Service Manual (Fuel Section) to clean and re-adjust the choke system on your carb. If the carb/choke are correct for your car, you should be able to resolve your choke problems in this manner.

If all the linkages are free to operate and you still feel the need to install an electric choke, go for it!!
