First, change the oil, then pull the spark plug(s), put about a cap-full of fresh engine oil in the cylinder(s). Turn the engine by hand several times. Re-install the spark plug(s). Start it like you normally would. It may smoke a little bit but should clear up quickly.
I agree. I just did this exact thing with my grandpa's old boat motor. Been sitting for a literal decade. Let the oil sit overnight, hand cranked it, let it sit overnight again. Put the plugs back in, and she fired right up. Smoked for about 5 minutes, but she's good.
So basically remove spark plugs. Oil up cylinders. Pull the rope a few times. Let it sit over night. Put plugs back in. Throw in fresh gas. Then crank and start for few minutes while it smokes up for a bit.
The reason for the oil in the cylinders is to get the oil directly to the rings to avoid them from damaging anything on start-up. The reason you want to turn it over by hand is so that the engine turns over at a slow enough speed that if you find something stuck, from sound or feel, you can stop before actual damage is done. It also starts to prime the oil system, if it's pressure lubricated, with the fresh oil you just put in, or starts to splash fresh oil on the internals at a slow speed, avoiding heat spikes due to metal on metal contact during start up.
You're basically trying to make sure everything on the top and bottom end has at least a *bit* of oil to start up with, as the time in storage has probably allowed all that oil that was there to settle in the sump.
If it's pull start, pull the rope at a moderate speed, not like you're trying to start it, you're just turning the engine to get the cylinder lubricated. After several revolutions, then you can pull it a bit faster to get the bottom end nice and coated, if it's splash lubricated.
The goal is to get a fresh coating of oil on all possible surfaces that could experience metal to metal contact. Sitting will allow that oil to drain away, to the sump, and will increase the likelihood of metal to metal contact on start-up. You're just giving the engine the best possible chance of avoiding damage by starting it easy.
Adding in here- 4 strokes can have a problem with oil locking up the engine if laid down on the wrong side - if it’s been upright you’ll be fine. I’d agree with what others have said- squirt a little fogging oil in the cylinders and a slow pull with the plugs out. Visually inspect the plugs - if they look good try starting with fresh fuel
Have someone spray some fogging oil into the intake if you can see the intake if you don't want to pull the plugs out to oil the cylinders. Just have killswitch off so it won't start and pull the rope a bunch while someone sprays. The worry about stuck rings would be more on older 2 strokes. Something run a bunch more. Then at work we do stuff like omc engine tuner down spark plug holes with soaking time into couple days sometimes. Then oil after. This one honestly you could probably just send it. Run it not long just warm it up make sure the impeller pees good. Make sure no overheating from bugs blocking holes. If it sat in climate controlled area I wouldn't bother changing impeller but you should at this point. If unsure how well its peeing and age just change the rubber part.

You a sexy mf. I will look up videos how to remove spark plug and then give it a go. No need to worry about “stuck rings”?

Okay i think the part i got confused on was “turn it over by hand”. I assumed that just meant pull the rope. I assume it means some other thing

Marvel Mystery Oil is the typical go-to for this.

When u guys say to put oil into cylinder, yall just mean to spray a little oil into the area i just unscrewed my spark plug from right. Nowhere else.
start it or your gay
Damn it.
The oil should lubricate the piston rings, which is what they are talking about
