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?

I’m sure you’ve already checked this off on your troubleshooting list, but were you using the 123 distributor when it was carb’d? If so, was it the same one? I could be wrong, but I was thinking that the D-jet one was different from the carb’d version. Could be another thing to look at.

It is the same. I bought the D-Jet version because I planned on switching back. I asked when I purchased the distributor and he said the D-Jet one will work with carbs and I had no issue setting it up with mine. The 123 distributor is awesome.
