i would also remove valves on the affected cylinder in case one is bent or not seated properly
Are you getting a constant 12v at the coils, Boyer say 9v, if no the ignition will play up, frankly you need to start at the beginning when put back together, a few years ago i had Z thou that would do this, everything was as it should have been apart from exhaust, i put an original system on, problem solved, still puzzled as to why it happened like that.
Just a simple thought but have you checked the fuel tank vent.... does the problem occurr immediately or after a few mins of running? Blocked or partially blocked vent wouldn't slow the fuel flow down immediately so a flow test might show up ok... but the flow would reduce after a while..
just a thought, I once had a faulty coil,worked ok on start up,but after a mile or so it stopped ,when it warmed up, that took ages to sort out
Got my cylinder head back with four steel plug inserts now installed. Hopefully get it back on and running tomorrow before I go away again. Watch this space!
the plug gap should be 27 thou, non resistor plugs, and resistor plug caps ,
