How in the heck does someone remove the choke butterfly and shaft from a holley 650 4 barrel. There are no screws and the shaft seems to be one piece. Should the blades come off the shaft first, or do I need to drill this thing out or what. I feel a little dumb asking but I am stuck..
Thanks...

There should be 2 Slot Screws that pass through the shaft and the blade. Remove the screws, pull out the blade then shaft will slide out.

that's a later style, you spread the shaft a little, enough to let the tangs on the blade pass.

Real question is, why would you want to booger up your carb like this? You realize that it won't help anything at all, right? There will be no increase in air flow, no increase in HP, no increase in acceleration, etc, etc.

Thanks for the replys, it is going to sent off to have the choke horn milled off and a little other work done to it. I am just trying to tear it down as far as possible before I send it out....

same story on the choke horn milling. That's a classical "marketing innovation". Even the briefest look down through the primaries immediately reveals that the area of the choke horn is huge compared to the area of the venturiis. Of course, carb vendors don't make any money off leaving it alone so.....
