I have a blackmax 150 v6 and am doing some pre season work on it. I ran it up today and thought it sounded like it was missing a bit. I checked the spark plugs and noticed that they have a bit of black oil on them. Is this normal. I dont know much about 2 strokes so any advice appreciated. Also past checking for a spark is there any way to know a cylider is getting enough fuel and firing ok.
Thanks for any help given

"Plugs on a 2 stroke NEVER war

"Plugs on a 2 stroke NEVER warm up at idle, so they tend to look dark and even wet after prolonged idling (in cold weatherespecially).
