AMC 1981 Spirit 6 cyl 258 with Carter BBD 8302S carburetor
The carburetor seems tight to the intake manifold, no rocking.
I retested the "open" electric choke, this time it measured 4 ohms, not
open. When I saw this I applied bat+ via a 1 ohm resistor (so I could
watch the current via the voltage across this resistor). The current
when down to 1A in a few seconds and after a few minutes was .35A.
At this point the choke was visibly open.
A later test the next day showed the choke to ground resistance
infinite/open.
