see my impeller is in the engine so the water runs up thrue the engine then round the piston out thrue the top next to the spark plug however this one is same as mine i mean identecall but it also has a feed inlet from the back of the barall ? so what do i do? just cap it off or? make a T piece ? you tell me

If you have a B1 or C1 Blata engine that will not work, I am pretty sure. Man I would love to have that for my 40cc Polini Rep engine, never seen one in America like that. You need a Blata 50cc kit, they have them at Tsunamibike in Canada, thats where I bought my 50cc C1 Blata copy bike.

Sounds good,my C1 has the wheels off and have to change to the SS racing exhaust, got some very soft slick tires, and my small tire changer works pretty good.
