Make sure your fluid level in the pump is changed and at the right level.

Did you try a new spark plug. Old one may have fouled.

I've never used it before what plugs in where, the 1210 powermate, Pictures would help

The hose connection I believe is for hooking a hose up and running it into a bottle of cleaner. The cleaner is mixed with the water when it is sprayed, The knob on the bottom adjusts the strenght of the solution. Most washers have the same setup.
