I just realized I’m going to need to pull the carb on a 1959 Electric Start Fastwin project I’ve been (slowly) working on for two years (I’ve just finished wiring up a new harness for it), to hook up the choke solenoid. When I got it, I opened up the carb, and found a new rubber tipped needle, but without the retaining clip (it also had a carbon "suppressor" spark plug wire), and I remember I was lazy and just bent a paper staple in the right shape. I probably also used model airplane dope on the old float, which there has since been reported to fail… So maybe I should just get a new BRP kit with a plastic float?
