Russian/Soviet 2T generator (part 2)

[Peandas]

So i am posting 2nd thread for all that requested pics and for some advice on next steps. Seems to be only factory test run..
-Has a lot gummy oil in crankcase(also has a crankcase drainplug hehe). Should i fill with diesel or some cleaner to get rid of 30 year old oil and then relube with 2T oil (bearings, wrist pin, piston ect..)?
-The slider on the electrical part is that voltage adjustment against load?
Front PTO is getting 75w-90 diff oil. I saved the old/new oil perhaps you are curious, i can send off for analysis, so we can see some Soviet master oil blending heheheheeee.
In Soviet Russia oil rust you

I’d guess that any preservative oil will wash out with the first run. I’d not worry too much about it.

However, a brief look at that piston and ring pack lead me to believe this engine needs lots of oil in the mix. They don’t appear to be chrome faced rings. I would strongly suggest 25 to 1, with a robust oil.

if it has bushings, then 16 to 1.

I’m just wanting to get rid of the preservative oil because its extremely gummy and I worry that perhaps it will block fresh oil from going where needed, even gumming up the rings..

you mean bushings at the crank with rod? I saw it has bearings for the crank itself. It will get Repsol 2T full synth.

The bushings can be either the small or large connecting rod ends. I’ve even seen one crankshaft end bushing on old two strokes.
