HAA = 1950 passenger car 216 engine Could HAA3b4772 be HAA364772?
All Chevrolet trucks through 1953 came with foot starters. Foot starters were available with six cylinder truck engines with manual transmission up through(?) 1959.
235 in cars equipped with Powerglide engines most likely came with solenoid starters.
235s on most 47-54 trucks trucks came with manual/hand throttle and choke controls.
Your photo seems to show a choke cable. The throttle cable would be installed downwards through the cable clamp on the carb - down to/through the top throttle "up-rod".
