bought a kit and installed it , cleaned the carbs, when I pump the ball gas comes out of lower and middle carb in what looks like a vent hole , the engine only started once, there is a little oil coming out of exhaust at hub, what is going on with this? fuel pump held with the plugs out. any suggestions would be appreciated??

When you rebuilt the carbs, did you set the float height? This could explain the gas coming out of the carbs.
 
You need a guage to measure the height of the floats. It might be easier to take the carbs to a mechanic and have them adjusted. They have the guage and know what height they should be adjusted to for your model. It is 5 minute job if you have the right tools. Good luck!
