Chain Rattle at Start-Up

[Jgkram]

I buy a one quart bottle so minus the 4 ounces in the gas tank means I put 28 ounces in the oil. To determine I have released enough oil I marked an old drain pan with a mark on the side equating to 28 ounces. I then crack the drainplug and unscrew it just enough to get a good stream and fill the drain pan to that mark. Just be careful you unscrew the plug a little at a time because, as you guys know, this oil comes out like a geyser. Good luck...
