John, I was able to log in now.  Sorry for the delay. I regristered the other day but never received the confermation or whatever and was not able to log tell now.   as far as the 880 goes I did take it and put it on the pump for a while but it was maxed out to pull it at rated speed lots of black smoke so i took it off after a bit befor I broke somthing or it decided to overheat.  ran about 20 min. deosen't start any better and still pops. I'm thinking of taking the injectors and having them retested. They do have all new tips. The tractor does run ok when warmed up or if you hold the preheat for a long time it will start and run decent untill the manifold cools off. I'm out of ideas. I moved the wheels in tonight and plan to take it to a plow day tomorrow if the hydrolic level stays up. Likly need to redo the pump next. I was maxing it out with that big disk and sopose I blew out a seal some where.  See how it runs out on the plow tomorrow.  Thanks for taking the time to help me out, Adam Suess
