All About Pocket Knives

I had a oil leak it seemed to be at the oil fill tube. Replaced the O ring where it goes into the block. Ran it for a few minutes seems ok.I want to check the crank case vent. I can’t find it. Tried to contact the company no help. Hope someone on AAPK knows. Thanks Harold

In my experience working on mower type engines the breather goes from the valve cover to the air box , done that way for emissions . Not sure on your mower but it’s a place to look .

Mike I thought about that, looked at the air filter it was perfectly clean. I thought if vented there would show some dirt. Thanks Harold

What Scoutknives said. Probably won't show up without you some bad blowby.

Thanks guys will try it next mowing day. Hopefully the O ring was the problem.
