What I do on my mechanical advance side carb engines for the first start is , 1) Ignition off , choke closed , wide open throttle , flip till gas drips from carb.
2) Ignition off , choke open , WOT , flip 3 or 4 times to draw charge into cylinder . 3) Igntion on , choke open ,throttle 2 clicks above idle , flip till pops ,return to idle
.
On electronic advance 1) ignition on , choke closed, throttle half to full , flip till it pops . 2) Ignition on , choke open , throttle at 2 clicks above idle , flip till runs .
Been using these procedures on all side carb engines for many years an still have most of my knuckles and fingers.
On rear carb engines I refrain from the choke until it drips part , as it usally ends with pulling the sparkplug and drying the cylinder . For some reason the fuel charge saturates the cylinder faster on rear carb engines
