7020 Allis. Has always been hard starting, even when it's warm needs a little shot of starting fluid. Parked it after we were done baling in the fall, and now cannot get it to start. No fire at all. Have had it about 3 years. Previous owner said he had replaced the pump and injectors. Good fuel to the pump, but just does not seem like it's getting a lot of pressure to the injector. Anyone have a good place to ship a pump to get looked at, or have a good used one laying around? The one that was installed has an electric shut-off solenoid. Open for any suggestions on what to look for next.

My 8070 (with 7580 engine, thus a roosa pump) was a hard starter. Evidently the starter was slowly faltering, so didn't really notice it. Starter finally went out, and we got it rebuilt. Spun er over very noticeably faster, no more hard starting.

Many times Roosa pumps tend to gum up from sitting if running bio diesel, and it is allowed to sit and age, it doesn't age well. Think of a jug of milk being 6 months old. I rebuild lots of pumps here. That is an M2/L2 pump. It could be made correct for a 7020 when rebuilding.

Would you be interested in taking a look at this pump if I shipped it out? Would like to pick your brain on a few things with it.
