Hi Gordon,

I've played with a C1Q ZAMA before (a different model by the looks of it) and didn't have a huge amount of success on the engine I used it for (high end lean out at 7000+) but it's still worth a try.

Pic 1: I did it the messy way, just hacking away until it was off. Lucky for you both needles are adjustable, my carb had one adjustable and one pressed/fixed needle.

Pic 2: Just cap it off some how. I wouldn't recommend crimping it closed as you'll never know when you want to use it again.

Pic3: I never removed the spring as the carb never progressed to flight status. Removing it may create some lateral shaft slop so be careful. I'd also suggest removing the butterfly and sealing off any holes in the throttle plate for better idle control. Thin litho plate secured by the centre screw will do fine. Watch which way the plate goes in, it only fits properly one way due to the various bevels/tapers. Yes, that's a pulse hole.

Pic 4: I left the idle screw in place, it will still provide a stop if needed. Removing the choke shaft will cause a detent bearing and spring to come out. I've run mine without this but be aware you could be letting air bleed in from the shaft hole. You could probably plug it with some fuel compatible sealant.

Good luck!
