Report "1994 PX 200 always ran well stands for 9 months of the year,usually starts with a huge cloud of 2stroke smoke after standing( I dont use the autolube ) now plug remains dry, will run fo a couple of seconds if carburettor spray is sprayed down plug hole and spark plug is quickly re inserted. I cant easily see the route of the fuel line and the location of the fuel tap. Any suggestions welcome"
