Thank you to all who helped and chipped in with precious information regarding my new old tractor. I now know it is an International Harvester 484 with Perkins engine and Bosch pump.
I changed the old fuel and drained the filter and managed to crank it up using ether. It fired up and ran, didn't have any knocking or whining, idled around 650 and could go up to 2000+ however it was blowing a cluds of really strong fuel-smelling exhaust, so strong that it actually burned the back of my throat and my eyes when I stood on the ground.
I know it isn't a burning oil smell so I suspect it is either out of timing or something is up with injectors or the pump.
I already ordered a repair manual for it and it is suppose to be here next week(Can't wait!) in the mean time I wanted to pick your brains for some precious info and see if you guys can point me in the right direction with troubleshooting.
The tractor had two fuel filters which originally were plumbed in series but it was changed by previous owner where he fed the pump via single filter straight from tank. Also the original tank has rusted through so the tractor now has a boat tank strapped to the back.
Also return line from injectors was plumbed back to the supply line using a "T". I tried to take the return line off that "T" and feed it in to the coke bottle but it didn't change a thing. The fuel was barely coming out of return line
When I loosened up supply line from injectors so some fuel would escape the engine seemed to clear up some and produced less smoke - that's why I suspect it gets too much fuel.
Please advise on what would be a first thing to check.
