Have you tested the glow plug take it out and check.
fuel lasts for ages if stored in cool dark place
reckon reason it aint starting is your flooding it.
dont run it too rich or you got no chance.
As for the plug RB no6 is a good starting point for winter.
glow plug is good, however it may not be good enough for winter.
its always been a engine that seems to flood easy, yet when run flat out does lean out too much.
i think my first starting point would be to get a glow plug that is made for these temps first.
