The saga continues. 1300 engine, dual port, new 30pict 1 carb, through an adapter. I installed a new vacuum advanced distributor and my timing light shows it is working. Compression test- all 110-115. As a result of previous problems, the right head was replaced and it may not be exactly the same as the left one.

 

If I short out the plug for cyl 1 or 2 the idle speed drops drastically. Shorting out 3 or 4 has no effect! The plugs for 3 and 4 are each the beautiful tan I would look for in a good running engine. 1 and 2 are the black of a too rich mixture. The exhaust from the left bank is noticeably cooler than the right and has less volume.

 

Since this would possibly be the result of a vacuum leak, I sprayed starting fluid on the intake manifold which had no effect.

As expected, the engine runs poorly.

 

Anyone have a suggestion what should be checked next?

I had a solution from a Samba person. Check firing order. Wow, interchanging 3 and 4 could possibly do this! No, it is wired 1432.:( But at least I wasn't that stupid.:)
