My DB 885 has a very aggravating problem. I'll be moving along bushogging a pasture when suddenly the motor speeds up like it's leaning out. It runs
that way for a minute or less, then slows back down to the normal speed where it was set at. It might do this twice, but then it slows down completely
and stops. I get off the tractor, work the lift pump lever for a few minutes, hit the key, get the motor turning over real good, spray just a little
starting fluid into the air cleaner, the motor cranks right up and runs fine for 5-20 minutes and then does the same thing. I just replaced the fuel
filters again and checked all the fittings for a possible air leak somewhere but can't find any. This tractor will not do this until it warms up to
normal operating temperature. I've never rebuilt the injector pump but I don't understand how that could be the problem inasmuch as the tractor runs
excellent until it warms up and all this constant stopping starts happening. Anybody got any ideas?
