with the engine off, look down the throttle bore and open the throttle,
you should see gas squirting into the throttle bore, I think in only 1 side
on that carb (primary side) unless this is a non secondary type carb then
both sides would get a squirt.
The way to tell is if you open the throttle and both plates open at the
same time, then you have a non secondary carb, but I think it's not
Also the primary side should have a choke flap at the top, open it up to
see down into the throttle bore
