On a Big Mig, holding the engine with the cylinder vertical and looking at the connecting rod, which side should the oil hole be on, left or right?

Thanks,
Rusty

Just as I thought. I've run into some righties lately and thought I should check.
Thanks for the reply.

Are the rightys engines that have never been apart?.....or ones someone messed with before?.....

You know......the guy who has trouble with CA but thinks he can double the engine power with a dremmel.......

According to the engine guy at Sig Mfg., as quoted on RCUniverse, when they were the Norvel distributor, the engines came in new either way. He said whenever he assembled one, he put the hole on the lead edge of the sweep as viewed at Bottom Dead Center. That's the way I put mine, but I can see good arguments for both directions.
