Bruce,

I've replaced the spark plug and bought a new filter. But it seems now that the mower doesn't want to start. It doesn't seem to kick over.

I've noticed a black oily sludge coming from the decompressor. Could this mean the decompressor is a gonna?

I tried the old trick of putting an old spark plug in the decompressor hole, but couldn't get it to start.

Regards
CC.
