Im (still1) trying to diagnose a starting fault on my 73 series3 ots which has been standing for years. I have (fresh) fuel pressure, compression, and fat sparks. It wont fire but will splutter if I spray fuel into air intakes. The plugs remain dry. Its a US spec so has lots of emissions pipework and Im wondering if there is a vacuum leak.
My main question is: On cranking the engine, should the carburettor pistons lift?

Thank you

There should not be enough vacuum to lift the pistons just cranking it on the starter. They will sit flat down on the bridge with the car idling.

Thanks Andrew thats all I needed to know

best
