Quote: Is the motor fresh? If so there shouldn't be any puff of blue smoke on start-up, should there? That seems a symptom of bad valve guides or seals. Maybe you have oil getting in where it shouldn't? Have you confirmed what is fouling the plugs? Just a thought.
are you sure it's blue and not just 'smokey' until it warms up? it might sound silly but i would smell it to see if it's oily smelling or just gassy smelling. that sounds so ridiculous !!
