Ok, the other day I posted a question about JD model B and which one to buy . Well the B's were junk. I bought an A instead. serial # in 535,000 range. They said it runs. Yeah Right I thought. But I bought it for 400 bucks. I hitched a ride for it from another buyer. Ok, got it home and I thought. Man how am I going to get this in the shop. Well I poured a little gas in the tank,. choked it, open the relief valves, rolled it over and in a matter of minutes it was running. drove it in the shop and shut it off. Ok, figured who knows how long since last oil change. Nasty looking grey water condensed crud. Drained it and filter. pored some kerosene in crankcase and let it drain. Is there only the 1 oil plug drain between oil pump plate and filter housing. What are the 2 plugs just rear of the oil filter housing? Its sitting in shop dripping right now till I hear from you guys what to check out on this my first JD , Thanks in advance guys.
