The backfiring and spluttering was through the inlet stacks when the throttle was opened from tickover when we took the inlet throttle bodies off there wes plenty of black soot in the front and back cylinder inlet ports.
Yes the injection pump has been timed according to the book and new injectors were fitted and tested several times. The pump had been stored for about 2 years with oil in and looked good. we did find there had been some attempt to adjust this pump by someone who compleatly adjusted it wrong and dissconected one of the links.
we bench tested the pump before re fitting it but this still may need a careful tweek after we get the car running
The engine has been compleatly re built new eveything including big end shells, pistons rings etc etc.
Ignition has been replaced and new leads and yes we have them on the correct plugs.
The Distributor could be causing problems due to the vaccuum in the one side of the engine not working causing the retard on the distributor to not work which we think is caused by the inlet port having pressure blown back through it from the inlet valves hence the cam timing being wrong.
Throttle bodies were also checked and re bushed where they needed it.
Yes the plugs are as black as after only a few mins running.

Hopefully we will get the Cam in this week and start it up again.

anyone got those measurements for the valves at TDC is it 2.7mm to 3.1mm

Keep the good info coming please
