1971 911 T with matching numbers engine suffered a fire in one of the Zenith carbs during the spring. It seems some molten metal and/or debris may have made it's way into the intakes and possibly two of the cylinders. The 911 has been at the shop for diagnosis and repair and they have managed to get the damage cleaned up and get the engine running again but leak down on 2 of the cylinders is 10% vs less than 5% on the rest. They also report lots of popping and spitting below 2000 RPM (it did not do that before). Advise the car is drivable as is for the short term but suggest I consider an engine rebuild along with replacement carbs in the near future. Well respected/trusted shop and mechanic I have no reason to doubt their diagnosis or advice.

So the question of the hour is this: If it were your money would your rebuild the 2.2 (stock or modified) and purchase replacement carbs? Or look for a good used motor of same or larger displacement for the same $$$?

My usage is pleasure driving, road trips, etc. No track days.
