g4200 h run away after injection pump rebuild

hey guys
I removed the injector pump due to a leak, which it was running fine at the time. put all new factory orings in the pump, fully disassembled it.reinstalled it and mounted it back on machine. bled system ,was getting a spirt of fuel with the lines off. mounted lines and started up, engine now is running away. it looks like it is getting extra fuel due to the amount of smoke being produced. I did also install a new intake gasket which has to be removed to remove the pump. I'm wondering if I could of installed the pump element that runs up and don in the housing backwards. does anybody have a assembly guid for this? thanks in advance

I check the delivery valves, they look correct, how does the throttle work in relationship to the governor. With the pump out and moving the throttle it does nothing, does anyone have a picture of the way it works?. I dropped the pump part into the little holding pin that has the groove for it. The only thing I am unsure of is which way the pump piston goes in. If the piston is in backwards would it get any flow, with the lines off I get little squirts of fuel out but do not see how the throttle lever controls the fuel regulator pin. Thanks for the help
