Thanks to all those who replied to my original e-mail.
When I went to pick the plugs I was told the guy made a mistake when specifying
W8LTCR plugs.
I fitted new set of W7DTC, and I noticed some improvement in the idle and power
of the motor.
I have also cleaned the ISV, idling was all OK afterwards, the ISV has some oily
gung in it.
Does anone use some sort of filter from crankcase breather hose?
I have seen some cone shaped felt filter in a local hose shop, I wonder if I can
stick one in the metal section of the breather hose (upgraded from the rubber
hose originaly fitted).
Any thoughts on the mater anyone?
