Yet another motor question('02 Suzuki 150)

[THEFERMANATOR]

For an engine that's been in storage that long, I would fill it with any oil it needs. For a 2 stroke like the 150, I would run it on 50:1 for at least an hour until you get the oil injection purged completely and verify it is working. Also before you start it or turn it over, i would put a tablespoon of MARVEL mystery oil in each cylinder and rotate it around by hand a few turns and let it sit for a few hours before you hook power up to it and turn it over with the starter. This will lubricate the cylinders and make sure teh rings aren't dry when you spin it around. Also it wouldn't hurt to spray it with WD-40 into the intake when you turn it over to put some lube down in teh rod and main bearings. I'm not sure what teh compression should be on that engine, but I would guess it should be around 100-125 if I had to guess. Just make sure they are all even with each other. And as far as the injectors go, I personally would have them ultrasonic cleaned before running it under load. I would do this for insurance more than anything as plugged injectors have taken alot of 2 stroke outboards to an early death.
