Hi, now revising the cause of fire. I now think that the fire was caused by fuel seeping onto the insulation wrapped round the manifold. When I stopped the fuel or vapor ignited. On the B16 the rear carb is very close to the manifold/exhaust joint. I often have fuel evaporation problem in carbs when stopped and idling waiting for traffic etc. The Rear carb had a seep from the base and was already due for new cork washers. I suspect that had I not had the insulation tape wrapped round, a new addition, the fuel drips would have just evaporated away from the manifold.
