New O.S. FL 70 Leaking Fuel / Oil. Mostly oil from rear engine plate. Help. Plsatic Warped?

Undo the rear plate bolts, pull it off and check to see if the gasket is warped/bent/deformed or maybe a smidgen of dirt is preventing full contact. Even if you can't see any dirt, clean it off GENTLY and reinstall. Remember to tighten the bolts crosswise a bit at a time, just like tightening the wheel bolts on your car.

Hi!
Isn't the oil just coming from the breather nipple on the crankcase...?

Regards!

Matt:

JanK has a good point, but it wont hurt to check the sealing also. Put some RTV on the joint as you reassemble, that will take care of any warpage in the plastic cover.

Bill.

I don't remember there being any gasket on the back plate? The oil is probably coming from the breather?

Enjoy,

Jim

Thanks Guys.
The bottom end was just set way to rich. Leaned it out from the factory setting and the oil stopped.! Thanks for the HELP.
