Now you could have gotten the wrong pistons and the comp. distance is down to far Pull one of the new ones and compair to one of the old ones here again it would not be the first time that what is in the box is what is suppose to be in there . I have learned over the years to check and double check as ya don't get what ya paid for . Also check your head and how the valve set in the seat as i can not off the top of my head remember if the valve stick out from the surface of the head or are below as on the german engines or any diesel this has a bunch to do with how well they will start i had a hard time with one machine shop over a 806 head because the put the valves in to deep and this tractor was hard starting on a hot day and lacked power . they had to redo the head and install all new seats to bring the valves back to where the BOOK called for then it would start down below freezen with out either and yes i know that they came from the factory with and either assist and do know how many engines that i have pulled down because of blow by because of the top ring or the top two rings were broken . If a german engine is in good order they will start with setting the shut down control to Cold start as this set the pump in a over fuel set . So like i said check comp. distance on the piston and the shape of the top of the piston with and old one and also check the valve protrusion or resession as to what ever that head needs and one other thing make sure that ya have the injector bleed all the way hope this helps . I am going to supper.
