How many hours do you have on those injectors? Have you ever ran any injector cleaner through the fuel tank?

Check the air cleaner for blockage.

Good point. First things first.

Black is unburnt fuel we know. All you have to do is find why.:thumbsup:

You're getting plenty of fuel and fuel needs air or else it will come out black from the exhaust. Most likely cause for insufficient air is a plugged air filter. May even have a nest of something in there.

Thanks for your response to my post. It's hard doing anything without a manual. I've tried to see what I could find out about the tractor,specs,drawings,and any diagrams.
