[T3] Diagnosis help for a badly running 1971 VW 411

The Type 3 dual carb engine overproduction has definitely been confirmed as being used mainly in the Type 2.  It was also used as an industrial engine. The engines were made before VW rounded up the numbers to the next 100,000.  Your parts book probably has production figures for chassis and engines, so it's not difficult to spot the discrepancy period. 

Our '73 Camper had a 1600 dual port single carb engine. The UK tended to g for lower spec models as more profitable to the importers (who weren't VW).

Yes, at least in the US, all our '72-3 Type 2s came with dual carb Type 4 
engines. In '74 they became FI. We didn't get a choice of engines in our 
Type 2s in the US, but I was surprised to meet a German who had 
something like a '77 with a 1600 engine. It may have even been a single 
port. I think he said they could even still buy the 1200 back then, but I'm not 
sure about that.

I don't know what else VW could have put Type 3 engines into. They may 
have been replacements, or maybe this was just another case of VW 
rounding up the end of year production numbers. It's always suspicious 
when the last one made ends in 250,000 or 500,000, especially when they 
also report something like 63,721 made up to 12/31 in the first half of the 
model year.
