Massey mf40 backhoe help with engine

[pbpimp06]

I rebuilt the motor I had the injectors rebuild also but motor sounds very sick sounds like it's running off maybe 2 shoot might be just the one it's a 3.152 Perkins in it how do you tell if the injectiors are not right or what would y'all think it could be ?
The injection pump never came off so it wouldn't be out of time right ??
Thanks Chris

The Shop I worked in had an injector tester. It was just a hand pump and a fitting to connect to the injector. I would get the injectors tested. sounds like they did a bad job or they picked up some dirt along the way, through the lines or in shipping. Ed

Did you prime the injectors? If not then they could be trying to inject air.

I had a silinderhead rebuild and they forgot to shortern the valveguides.......rockers bent and engine missed .

Ouch! Hope they fixed the engine for free. Did the valves hit the cylinders?

All the aferrepaires was done for free
