Engine lags and stalls when initially pressing gas-Solution Found?!

Check the gap in Choke plate, too much can cause the wee carb a problem of choking on too much air, also agree with checking the Accelerator pump.. the clip looks like a bent paper clip, and yes it will come in a rebuild kit. I own Three of these BBD carbs, used in pieces one Brand New that did this and One on my 318 now that I rebuilt out of 1st used one and 2nd..
