I am new to posting but have popped in time to time. I bought this mep003 on nice trailer a few years back. When I picked it up from a base in Maryland, the injector pump was off. I put it back together, timed it and it started and did everything it should. One day, it did not start and I came to the conclusion it was the injector pump. I found what they call oldham plunger retainer broken inside. I searched and found one and put it back together and it ran fine for a while. We just had a hurricane here on the shore in NC and I thought I would be doing well with all this power. I started it and it ran 10 minutes. I shut it off and it would not start again. I pulled the pump again and that dogbone looking oldham retainer was broken again. I could not get another soon so I had a buddy braise it. I spent another hour filing it and fiddling with it. I timed it and it ran five minutes and broke again. Now my question: Do these break that often am I doing something wrong or is there something to adjust that I don't know about.
