Oliver 1600

I have an Oliver 1600 gas that I got from my uncle, the tractor used to start great even in the winter. Now it sometimes turns over real good, other times not very well, and it will turn part way then almost stop. I"ve had the starter rebuilt and it still does the same thing. Also it turns over alot harder when you pull the choke out. Added to this it leaks radiator from the rear of the engine when it gets warm. Possible head gasket issues? I would appreciate input from more experienced people.
 

Possibly you could tighten head bolts to stop leaking water, but I'm not real good at mechanical issues up close, never mind at a distance.

On the starter not spinning with the rebuilt starter and a good battery, I would look into bad connections at battery posts and cleaning them, and possible bad wires from battery. Battery cables can go bad under the insulation and not be appearant. Do any of the wires from the switch get hot when trying to crank? It's possible there are bad wires there, and, some body can correct me if I'm wrong, but a bad switch might be an issue.

Since its a gas burner the hard starting sounds like vapor lock. Check the fuel line and see if it has gotten bent up where the fuel would be restricted to the pump or if the fuel line is laying on the block getting hot. Could be the fuel pump is weak or carbuerator needs rebuild. Mostly you get vapor lock when you shut off a hot engine and then re-start a short time later but different factors affect this -- I would check everything from the fuel tank to the intake out good. The water leak may be a freeze plug about to rust out if from the back of the engine.

Could be head gasket and antifreeze hydraulicing one cylinder causing slow turn or near stop of cranking. When it does start does it spew crap out the exhaust?
 
Check all battery cable connections. They should be thick cables, 0 or better. Not thin things like a car cable. Might not hurt to replace them.

Also might not hurt to pull the plugs and spin it over. If antifreeze spits out when you crank it over, it's leaking coolant into the engine. Also an easy way to find this is pull the dipstick. If it looks milky, it's getting water in it somewhere. That doesn't guarantee it's coolant, but it's one of many possibilities.

If it's leaking coolant into the engine, it's more than likely a blown head gasket. Sounds quite possible since it's leaking coolant at the rear of the engine when warmed up.

I also own a gas Oliver 1600 with the 248 motor which I keep outside, and have found that unless I replace my solenoid every couple of years I have this same problem. I haven't had to replace the solenoid on any of my other tractors. A good way to test this is to jump the solenoid and see if you get a nice fast cranking speed.
 
Be careful doing that. We had a friend get run over this spring jumping the solenoid and was run over and is, luckily, still recovering.

I'd crack the drain plug to see if you've got anti-freeze in the oil. That would be a good sign of a leaking head gasket or cracked head. Most likely head gasket if its on the outside but good to check insides too as antifreeze will wipe out bearings pretty quickly.
