is it possible to disassemble throttle on these carbs?

I guess the answer is yes, but has anyone done it?

I had a spare carb body and I tried taking out the two
philips head screws which attach the throttle to the shaft.
I was unable to do this.

Yes.......

So tell us your secret. The screws seemed to be completely stuck on my throttle. The fact that you have to use a tiny philips screw driver made it almost certain that they will get stripped. Which screwdriver did you use to get them out? Do you have the worlds smallest impact screwdriver?

Yes the throttle shafts can be removed, BUT be warned, the butterfly shaft screws are "staked" with a punch, which flares the threads. This is so the screws cannot back out and get sucked into your engine. Removing those screws is almost impossible without stripping the screw head.

Question is why do you want to remove them ?? You will distroy the screws, your dremel will be usefull

There are seals along the shaft which are bad on the 550's carbs. They leak a little fuel and cause grime to build up. They're also probably leaking vacume. If I could remove the shaft I could fix the seals. But the crimp on the screws is a problem. I guess I can drill them and find replacement screws if I really wanted to.

These are very difficult. When you replace the screws you will need to "Cripple" the threads by using some lock tight type product that will insure that you done't lose one in the motor.

Thats very important......
