Just recently changed my 1963 230 c10 to the twin 32/36 carbs purchased from Langdon Stovebolts, everything is fine until i have driven about 30 miles then its starts to splutter and dies, i reduce the speed from 50/55 down to about 40 and it will pick up again, the more miles i do the worse it gets, i can even be doing 25/30 and suddenly its cuts out but taking my foot of the accelerator, then putting it gradually down again it will pick up but sometimes splutters, going to do a 700 mile trip in July and i dont want to be stopping and starting
