I did search and I found nothing.

Is there an advantage of using a 21mm carb or a bigger one over a 19mm carb if you are running a 70cc kit? Will it just go through fuel much quicker?

Thanks.

Thanks.

Dekker aka www.50cc.nl or www.jollymoto.nl has 28mm carbs for zuma's as well as coomplet carb kits.

Thanks for the links. I saw those web sites before, I could never find parts for the zuma on that site.

What model is the 2004 Zuma, I have the service manual and it says that it is a YW50AP. If you could possibly help me with that. Thanks.

Wouldn't a 28mm carb be a little big? If it is just for street driving.

Thanks.

vert/horiz? Does the piston run up and down, or side to side?

I believe the motor is a horizontal one.
