Thanks Scott, I'll have to go through my stash of goodies to find a suitable glow plug.
I have an OS "F" plug on hand, but I'm sure I've got a YS 4 stroke plug hiding around. I'm not keen on drilling holes in the belly pan but I'll sort out something.
But stuff me, I've got 3 cdi modules, 3 cdi sensors and a bag full of new and used spark plugs to swap around, how many do I need!!!
Cheers
