I reassembled the pull start with gas tank then rested it on top of the chassis without bolting it in so that I had a means of turning the flywheel at a better speed. Spark was there on both plugs.
Also roughly checked the coil alignment / airgap using the method fleetwin mentioned though it was already pretty close.
So I’ll get back to cleaning up the tank, replacing the gas line and adding an external fuel filter (part on ebay you can recommend?).
Fleetwin, I will use a torque wrench so that I can bot that flywheel down properly!
