Making kickdown lever for carb

well this has become more a of PITA than I expected! I guess the lever on the carb is stainless and I can't manage to drill a hole in it. I can not take the lever off so I have to use a cordless drill, I put a block of wood between the lever and the carb body so i'm not putting excessive pressure on the shaft or trying to bend the lever, using low drill rpms and using oil. Need to drill an 1/8" hole i tried using a 1/16 as a pilot but broke the bit pushing too hard even with the bit all the way in the chuck so only 1/2" was sticking out. I can't figure any other way to add the lever i need either for the kickdown.

I'd love to just ditch the 904 and have a manual but i can't imagine where i'd put the clutch pedal in my little roadster
