Carb base insulator possibly missing?

Yup or maybe a vacuum leak, bad base gasket or a leak somewhere else.

Try dribbling gas down the carb throat with a small squeeze bottle and
see if it idles (fast).

You can listen for a vacuum leak with a piece of small hose. Hold one
end up to your ear and probe with the other. It helps to stick a ball
point pen barrel or other small tube on the probe end so you can
control it better..

You can also get something like Cyclo brand Carb cleaner (or other
volatile spray. DO NOT USE STARTING FLUID. Spray it around the hoses and
junctions and see if any of them makes the engine rev up or changes the
rpm. Be careful not to get fooled by putting it in the air cleaner But
it's a quick way to find a vacuum leak...
