ok so gave it a go tonight.
Tried to start it just to see. and it went first pull?
Waited for it to cool and then it wouldn't start. So sprayed the starter spray on the carry and it fired up straight away. Is that what you meant Norm? If I spray ON the carby and it starts it means there is an air leak BECAUSE the starter fluid has found its way into the engine?
ANyway, changed the O rings on the manifold. And while doing that noticed that the wires connecting to the coil were loose and covered in Poo. So cleacdned them and clamped then on a bit tighter and sprayed them with some electric connection spray stuff.
Put it all back together and second pull start. Let it run for 10 mins. turned it off and again second pull start!! Success! At least for now. See how it goes on the weekend.
Also, Gadge and freebird, I tried to remove the flywheel and it wasn't moving. So for now the ignition module is going to stay in it's position until I have another go at removing the flywheel.
