So you drag a tractor out of the weeds that has sat for who knows how many years. You want to try and fire it up without causing any damage that isn't already there. Do you squirt some oil in the plug holes and let it set a bit? Do you use channel locks on the crank stub and turn it once or twice by hand? Do you drain the old oil and add new or just if it looks contaminated? What tips and tricks are you folks willing to share?

I like to pull the head and have a look-see.  If there is rust it needs removed before the engine is turned or damage will  result.  Also helps to know if it was worn out when parked.

A bore scope that you can get off Feepay for around 10 or so bucks works great on most USB smart phones, or, like us older folks used to do, about 10 oil can shots in the hole then let it sit for couple days. Once trying to start, I also like to use oil mix gas when trying to start an engine thats been asleep for...??, extra lube...of course! Cheers:)

A trick I've heard of for seized engines is, transmission fluid and diesel fuel, pour that on the cylinder head and let it sit with something like a pail of sand on a pipe stuck to the flywheel.

That should free her up, no effort on your part either...

Got this trick from a friend of my dad. It was used for big motors though, not GT sized motors.

Not quite sure pouring anything on the head head will work?

What I do is turn them by hand at least a full revolution,

If it turns freely then check for oil

then see if it cranks and check spark

then introduce fuel and see if it fires

if it does then I go through a cleaning process and

change the oil

Depends on the engine, on the old Kohler K twin horizontal opposed, it's hard to get the lubricant all the way around the piston, I agree with above, pull heads ,a good de - carboning can't hurt it anyways. If a vertical I pull the plug ,if I can't turn the crank by hand on the pulley I fill it with Kroil and let it set, if it turns over I use fogging oil and let it set, drain after a couple days to a week , change the oil and figure I'm going try starting it.

I meant on top of the cylinder, in the combustion chamber. I often am not too great with articulating ideas....

i normally like to pull the head & clean to make sure there is no carbon burn around the valves to free and stick the valve(s) open when trying to start them , other wise i just pre lube with some 2 stroke fuel if not seized
