Thank you for your comment. Where did you connect electric choke wire?
I have a 12v converted '55 and connected the electric choke wire to the 12v / input side of the ballast resistor.Thank you for your comment. Where did you connect electric choke wire?
The 4160 pretty much approximates the original Autolite 4100 the factory put on your 390. I have found after doing 3 of these that the Road Demon 650 bolts on perfectly, was setup perfectly out of the box all 3 times (I just did minor idle adjustments, the jets were perfect, sight glasses to set the bowls, throttle cable was perfect length) and gives you a bit more punch than the 4160. And btw Demon carbs ARE actually Holley, and our moderator will be MORE than happy giving you a sponsored link to their sale on Amazon. They sell below the 4160 last I checked (a while ago) too!
