..some thing over heating, my thoughts indeed.
piston and rings seem ok. But I've not got kit to do a proper pressure test.
manual choke. don't think it's that.
I was thinking spark plug breaking down, but it's only a few weeks old (could be some fault in it though?)
Possibly the 'coil' We did have a plug fall off it last week. Not so simple this time. Maybe inder load, this is heating up and failing? But then when spark plug out of head, it is sparking
as it's a 2 stroke, not alot of moving parts.
There's no vacuum pipe from card. Just fuel in, oil in, over flow and throttle cable.
