Hello, I have a couple questions about my Oliver 1750 Diesel. First, my wifes grandpa farmed with Olivers so my father-in-law is hooked on them and when it came time for me to have a tractor for our acreage he found me this 1750. I know pretty much nothing about tractors so here I am asking you experts questions, very basic, but I want to learn and take care of it. First question where can I get a good owners manual for checking fluids and what types of fluids it takes and just the basic use of it? I bought an I&amp;T shop manual already. Second it starts hard, I have to use starting fluid (carefully of coarse) to start, even after it has been warmed up if I let it sit for 10 minutes or so, as it cranks the exhaust is black which makes me think it is getting fuel, when it starts it runs smooth and revs up fine. If you have any advice or answers I would greatly appreciate it. Thank you. Bud
