oil leak, 1986 50 horse 4 cylinder...

[Scott Kirkman]

I've got unburned 2 stroke oil leaking out from under the flywheel. I thought it was the crank seal, I replaced that and I'm still getting a leak. What else should I check? As far as I can tell, all nuts and bolts are tight... Also, I'm getting a periodic surge at full throttle. I'm wondering if it's related to crankcase vacuum...

Could there be a bleed return hose that's leaking?

I think there is a small hose that pumps up a fuel oil mix and lubes the upper bearing, make sure its attached to that small nipple under the flywheel and also not chafed.

I replaced mine with new yellow poly vinyl looking stuff used for weed whacker fuel lines that I got at the local auto store. No more leaks.

Stator and trigger are both new and not leaking. It's definitely 2 stroke oil. I'll check the oil feed hose when I get a chance. Thanks for the tips!
