checked the fuel in the float bowls of one and two by draining them into a aerosol can top and measuring and it was 5mm higher in one so hoping your right mike. have pulled the carbs and changed the o ring, checked over float heights et too ill put it all back tomorrow hopefully its sorted. the old o ring was undamaged but definitely weaker/softer, hoping if thats what is the problem the rest will be ok but if another goes i'll change them all for genuine yam items
