Well that went well, put a new plug in and it started on the 2nd pull, thanks. Although i literally drove out the garage, up the drive and on way back down hit the wheel off my real car and broke a rear wishbone on the marder typical.
That was the spark plug i pulled out, had a jet black hard layer over it all, it washed off with white spirits, could my engine be running too rich still? Seems a bit smokey on acceleration.
