How can I fix my Leyland Ambulance 1972?

have you checked for a spark at plugs if there is it may be fuel fault - could be drawing air through rusted pipe or elbow on tank where pick up pipe fits.if there isn't you need to check feed to coil if ok check feed from coil to dizzy, check feed through points [with points closed] if no feed points at fault -may just need cleaning and re-gapping
