Thanks Alejandro,

I'll pop it back up to 20% and work out some glow driver arrangement. I can fit a normal Ni-cd through the cdi switch (cdi removed of course) and wire it down to the glow plug and have a helper switch it on once the engine is turning (or make up and electronic delay?).
I am waiting on a new sensor/disk valve assembly to arrive and will try that first.

I don't have the holes in my cowling to access a glow plug so I have reluctant to try that, it is a last resort option. I might make up a "drop-in" system as a backup, so in the future I can pull the cdi and swap over to glow in a matter of minutes should I have problems at a comp.

I just wish whatever is causing the problem would just stop working so I can find it rather than being an intermittant problem...[:@]
