Has anyone made a choke/ventrui pulling tool ?

Got a set of auxiliary ventruis and chokes that are proper seized in the body of a DHLA. I've put a heat gun on the carb body and beat on them harder than I wanted, no dice. They are stuck like chuck. I think I can make a puller but thought I'd ask before striking out on my own. Ideally I'd like to pull these without doing enough damage to make them unusable.

You have taken all the locking screws out?

I have not made one but this one looks like it'd be easy enough to copy.

Yep. Carb body is completely stripped sans the choke and ventrui.

If the venturi is not binding elsewhere, the problem point could be the invisible small tension spring holding the venturi in place at its base.  (i) Squirt some lube down and into the small channel in which the spring travels to lubricate the spring, (ii) look through the throttle plate end and find a choke or venturi part, ledge, etc. that might accept gentle taps from a wood dowel, brass bar, or equivalent, and (iii) try tapping the stuck parts out.

 

I have never done this; however, it seems like something to try.

Yes I made one. But it's in storage - I'll take some pics the next time I'm there
