Hi I've owned my massey for almost 3yrs now . bought used w/ 117hr on it. fluids/filters were all changed before purchasing. I just started having a fuel issue where I was having some random hesitation power drop off. So I changed the fuel filter and it was pretty dirty. After I cleaned it out ran great for a couple days and then I started having the hesitation power drop off, where I hit the gas and wont even rev up and it dies. So I'm wondering what should I do next ..... Check out the injectors , pump? not really sure where to go from here. all help is appreciated.
