magic mike, you're just the person I need to talk with about this. What type of screws did you use for the bottom adaptor, and did they interfere with the spacer? What CFM carb do you have? Also, how are you going to setup your throttle cable?

I've got to figure out what the best way to hook up my trottle cable will be. This is on my '68 C-10. I'm also going to lean out the carb I have. I'll probably start out at 6% lean on both the Cruise and Power modes, and see how it goes from there. Thanks for the help guys. John
