Ossa crank seals

Hello guys, I've got an engine for my Ossa project... comes from a late 70s Pioneer, I think, as it's got the coarse teeth on kickstarter and gear lever.

The engine starts but it's drinking gearbox oil, I think... it's impossible to jet and smokes bad. The smoke is also very dense and isn't easy on the throat.

I asked several shops... some will do it but I'd have to ship the whole engine block. Some others won't touch it with a 2 meters pole (most of them).

I've just bought a Beta M27x1.25 puller for the flywheel and plan to get a bearing puller to grab the cush drive. The good thing is, I have an Explorer engine partially seized I can experiment on, before I work on the good one.

Also think I've found the seals measurements. The Motoplat stator should be good on both engines, so might end up selling the one on the partially-seized Explorer engine. Is it worth disassembling completely or best kept in one piece with head and cylinder still in place?
