Re: Electric Choke
They work just fine when set up correctly, which most people don't do.
Process is thus:
Mount choke, set power up, good source is the IGN terminal on the fuse box. Do leave the old hot air inlet OPEN< use the screen provided, and do not close it off, the choke stove inside the unit needs the very slight vacuum pull to make sure the stove doesn't over heat and fail.
Now, adjustment. After the entire choke is installed, power it up with a jumper wire with alligator clips so you don't have to leave the ignition on to set it. Slightly block the throttle open to allow the choke linkage place the fast idle cam OFF holding the throttle open. Rotate the choke stove to completely close the choke plate in the air horn. SLOWLY open the choke, then close it to the point the choke plate just closes completely, tighten stove retainer screws. Disconnect jumper wire power to the choke, restore car power to choke stove, REMOVE THE THROTTLE BLOCK TO LET THE THROTTLE FULLY CLOSE. Done.
Choke stove: the heating coil inside the plastic cover housing.
