First off, I would like to say thank you to anyone who takes the time to help me think on this.
Background
I had a well-running 1987 740 turbo that I had in good stage 0 condition, until I decided I wanted to swap a V8 or similar. Engine was a 95' vintage NA squirter block with a stock head, turbo, injectors, etc... Ran very well for several thousand miles and rallycross events before pulling. Engine and transmission was pulled and a nice 242 came up for sale, so I bought it to stuff the B230F+T into. The engine has been converted to a block mounted LH2.2 distributor, and the 740 harness has been made to work in the 242.
The problem!
After swapping and LH2.2 B230F+T into a 1978 242 project, I am having problems getting it to start and run with correct timing. The spec for these engines is 12? +/-2 at idle. So far, the car doesn't want to start until the timing is advanced to about 18-20?. During cranking, it acts as if it is getting either no spark or no fuel until I advance the timing to this point. Sometimes after the starter is let go it will sputter once or twice, when the timing is lower than 18-20?. Once it starts, it also seems to have a miss at idle. Does this sound like something in the electrical system is funky?
What have I checked?
I would really appreciate any thoughts, or ideas that you may have. Cheers, and thank you.

- Timing of cam, intermediate shaft, and crank are correct
- Timing mark on crank pulley matches timing cover when at TDC
