Weber Carburetor for Slant 6

Your carb looks to be a 32/36 electric choke. It is a progressive two barrel, in other words when running at less than half throttle only one barrel operates than as throttle is fully opened the second barrel opens.

When you electrically connect your choke use a relay triggered from ignition circuit, and power heating element from ¼” bolt at starter relay, or ¼’ power lug on alternator. This will limit any voltage drop seen by voltage regulator induced from directly connecting choke heating element to run circuit of ignition, and reduce over charging problems related to voltage drop caused by a parallel resistance (coil & choke) to ground.
