I’m rebuilding a set of pretty nasty carburetors and want to completely disassemble and vapor blast. I need to remove the screws from the butterfly throttle valves and remove the throttle shafts. I see the screws have been factory crimped to prevent loosening and dropping into intake ports. Good idea, until you need to take them apart, especially with aging and additional rust. Could someone with experience with this situation comment on removing the screws? Thanks!
