Hello all,
I just picked up a slightly used Yamaha Vino 2-stroke. It is in great shape, but notice that 0-20 mph acceleration is very slow. The scooter has been sitting a long time with only 384 miles on the odometer. I cleaned the gummed up air filter and changed the dirty, oily spark plug, but it is still not running right. What's next?

Cleaned the carb just now. It was pretty clean to start with. The fuel filter is a tiny net/bag thing in the fuel inlet. Cleaned it too. I plan on replacing that with a regular inline fuel filter. Acceleration on the center stand is still not stellar. I will adjust the idle on the fuel mix next.

I adjusted the idle and mix this evening. It is running much better now, but I didn't have a chance to take a test ride.

I have a 2001 vino( 2 stroke) sat for 13 yrs, drained the tank put new fuel in, kicked it and it started no trouble,starts every time with a kick(obviously battery done). Will rev up at start then dies to bare idle. My thought is the fuel filter only letting enough fuel to keep idle after it drains the bottom end. Where would it be?
