Yanmar 155 D help ...please

[snowman6363]

I am a new owner of a 155d, since i bought it, when starting it makes a banging sound (sort of like a rod knock) however when i pull the decompress lever there is no sound, that being said the tractor would start fine and run fine other than black smoke when accelerating.... i was using it one day when all of a sudden it lost power, i changed the filters but with no luck, any suggestions or does any one know of a repair shop near clevealnd ohio where i can take this to.. i called several folks who all said that they could not fix it due to unavailibility of parts

thanks in advance

ok i did a little bit more investigation... I removed the injectors and found that the rear injector was not spraying fuel, i disconnected the injector and both line had fuel flowing, i even swapped the injector and still no flow to # 2 cyl.. how hard is it the rebud one and does any one have any advice
