Default Anybody remove the choke tower...

...from their Holley carb? I've got a couple 4150's I'd like to do this to.

Thanks!

This a great way to get more air into the carb. If you look at the clearance between the low profile air cleaner and the choke horn you'll see that air flow is severly restricted. The best way to remove it is to disassemble the carb and take it to an experianced machine shop for milling. I run a Holley HP model which has the choke horn removed from the factory. As far as start up is concerned, a couple of squirts from the accellerator pumps and your engine is primed.

I found a slick and easy way to remove the choke horn, I chucked a cut-off wheel in a drill press and set the table height, then rotated the carb body into the wheel for a perfect cut

I use a die grinder to remove the choke tower then blend and polish the venturies.

Thank you for the tips guys. What about the brass tube thingy (sorry, I don't know what it's called) that appears to be cast into the tower? Do you just cut around it?

I used my trusty Dremel to do it.

dremel here also. You want to leave the brass tubing thing. That's where gas comes out when the floats stick. Should connect the front and back tubes with a piece of hose with a slot cut in the top of the bend. This way the gas will drop in the carb instead of going all over the intake manifold.

I mill mine off and then use a die grinder for blending. To remove the brass tube thingy use a drill bit, find the drill that the shank with the tightest fit but still get it inside the tube then use vise grips with the drill shank installed to prevent collapsing and the tube will pull out easy. I cut mine down a little for low air cleaners.
