D-Jet Conversion not going as planned., Car starts but will not run. Options

[slapshot]

I am converting back to D-Jet and my car will start but dies right after. It will not rev up applying throttle. I have a 1975 914 2.0. It was running great with Weber 40s prior.

The D-Jet system is from a 1974 2.0. All the parts came in visibly good condition. TPS calibrates good, AAV tested good, Thermo sensor good, air intake temp sensor good, and a new cylinder head temp sensor. The only test that I think is failing is the vacuum test on the MPS. It leaks. Video of testing the MPS.. The MPS has also been rebuilt at some point. The original part # has been removed. There's a good chance it is not calibrated for my car. I have all new vacuum hose and fuel pressure is between 28 and 30.

I don't have any tools to calibrate the MPS. Should I try turning the inner screw on the MPS to see if it helps? Or should I send it to someone to have it rebuild again and recalibrated? If the later do you have any recommendations on who to send it to?

Now the BIG issue. I am working on setting the timing. Remember that I started with a great running car with carbs that I did all the work to get it working good, did all the carb tuning, installed and setup new 123 dist, etc. So its this isn't my first time. I set TDC based on plug 1 on the rotor, follow the instructions from 123 website, set app to 20 deg for all RPMs, try to start the car but it wont start. I guess I had the dist too loose and it slid up and out of the groove so the rotor wasn't turning. Here's where it all goes bad. I set TDC and verify by using a leak down test (easier than removing the valve covers) to verify the valves are both closed. The issue is TDC for #1 is about 180 degrees off what it was before. I have double, triple, quadrupled checked this and pulled the valve cover off to verify the valves are loose. What am I missing here? Is it possible that the dist gear moved? The dist didn't pop out of its hole that I know it just slid up a bit. Could the 123 internal drive slipped? Could I have had it wrong with the carb and ran it all summer? I think I've lost my mind.
