Fresh 2.7, doesn't want to wake up Options

[930cabman]

My /6 conversion is going on 3 years as it seems as many do. I had a local old school reputable shop build the stock 2.7, case was done at Ollies, .... should be a great engine. Finally trying to get her barking, but just won't take hold. While cranking she wants to start, but when I release the starter, she conks out. We have a spark (not real significant), timing is close, carbs appear ok.

Is it possible the valves or maybe rings are not sealing because the engine sat for about 2 years?

I had the same issue with the 2.7 that I put together for my 68 911. I did all of the compression, spark, fuel verification. There were two issues. I was trying to run the 2.7 without a CDI box and fuel pressure was too high. I thought, they used to sell these cars with Weber carbs new and they started and ran nicely. I went back to the initial settings for the Weber’s including low speed mixture and ultimately fuel pressure at 3 psi. I installed an MSD 6A ignition. It then started, idled and took throttle nicely. That MSD does pack quite a wallop when I tried to put a loose plug wire back on even using insulated pliers.
