Looks like it was sealed up nice and tight.

 

Yep base gasket wasn,t gonna leak.lol

I,ve yet to buy an old quad or snowmobile that hasn,t been butchered in some way.Stuff this old has has too many hands and years for people not mess something up.I never take anyones word for it.

Bought my 500 in pieces with cylinder already off but bottom end was clean and supposedly rebuilt.Once taken apart the counter balance gear was missing a tooth,bearing completely missing on the power valve and crank wasn,t pressed fully and was rubbing on the cases.And this was rebuilt by a cycle shop...Nothing surprises me.
