It's a 2001 Twist N Go scooter, disregard the category below (limited options). It's a 49cc 2 cycle 1 cylinder engine. I just bought it and cleaned the spark plug, it was very hard to start before that. It starts pretty well now, but is kinda tricky to keep idling and doesn't seem to be super zippy sometimes, like when I roll on the throttle hard. It's is blowing copious amounts of white smoke and black oil out the tail pipe. My guess is too much oil being injected, am I on the right track? Thanks for any help!
Replace the gas and make sure fuel gas mixture is correct.
If the smoke is black you need to lean the mixture with your mixture screw on the carb (below air intake) if it is white smoke needs more oil on the oil adjusting screw (below or above oil line ) tune it in until you have a good idling noise with back tire moving at a slow and steady pace and you should be able to stop the tire with your foot and spin it opposite direction with no interference after that's all done make sure your throttle line is taught with one of the two adjustments on the carb or by your handlebars it should take up any slack you feel on the grip then you're good to go I smell gas and oil but barley see them on my scooter and it runs very well on low and high end speeds but will vary in weather conditions
You can get low smoke 2 cycle engine oil, that will reduce the amount of smoke that comes out the tail pipe. The best stuff is Blue Marble.
That is all I know.
Replace the spark plug 2cycle engines are hard on plugs also sounds like it needs a carb cleaning black smoke means carb is fooding

Yes it has a separate oil tank and the fairly useless owners manual calls for 2 cycle injection oil. Thanks for your help!
It's blowing white to light blue smoke, NOT black.
I pulled the spark plug and cleaned it with a wire brush and checked the gap, it had good clean edges and after the cleaning the engine fired right up.
My question was...
when a 2 cycle oil injected engine runs but is blowing alot of white smoke and black oil out the tail pipe, then what is out of balance?
Take it and run with it Cape cod bob! Best wishes.
does it have a seperate oil tank or do you mix in the tank?
