Does '73 electric choke need exhaust heat crossover in warm climate?

The electric is a "helper" due to the 68---later on smog regulations, was an attempt to get the choke to open quicker. The main thing that operates the choke is engine heat, not the electric heater.

Only downside to blocking a crossover, even up here in N Idaho........is maybe a little stumble before warm-up on cold days.

If your mechanical choke thermostat is properly free, working and installed, you should be able to adjust it a little "warmer". Also make sure the vacuum pull off is working.
