where to start ? .....how much vacuum do you make at idle in gear , possibly the springs under the metering rods are wrong , the rods need to stay down idling in gear with the top cover plates plates out of the way if they do not you need lighter springs , as I said raise the float level , 7 /16 " is too low not much you can adjust , make sure it is not flooding with dirt in the needle & seat causing it too stall , is the timing retarded too much , is there a vacuum leak in the power brake booster causing stalling whne the brakes are applied ?
