I guess I should start a new thread here. My question is this I have a MF25 which I have owned for 15 years. Several years ago I ran some bad fuel through it and trashed the injector pump. I had the pump rebuilt, injectors cleaned and tested, new lift pump. Everything was reassembled and it ran okay but it smoked at idle. Not just a little but clouds of gray smoke. When the motor is run at 2000 rpm or so it clears out and is fine. The old guy who did the dissassembly and reassembly worked on it several more times and finally said that the motor was worn out and it was burning oil. He has since died. I think he didn't do something correctly and it is unburnt fuel. Out of time? It has since started blowing by one of the injectors and hasn't run in several years. I should probably cut my loses and give up on this thing but it was always a good machine when it ran. I'm trying to come up with a plan of action. I wonder if I pull the injectors again, have them cleaned and blow out the fuel lines, new gaskets/ seals for the injectors. What I am wondering is, is there a tune up procedure for the 107 Perkins engine and if there are any parts available (gaskets etc). Any help would be welcome.
Mike

You could contact Perkins for parts and maybe a service manual. ....

If grey smoke sounds like water in fuel.white smoke would be a worn out motor,black smoke is to much fuel.
get a good fuel additive and run that with your fuel..
has it lost power? I bet not,just smoke.. ....
