Default Stover 1 3/4 K newbie help

I recently purchased this Stover. It has obviously had a bit of work, and strange white paint in the hopper. The previous owner said it had new rings, and new bearings. I know there is a bit of break in with rings. When the engine is running there are bubbles that come up into the drip oiler. My question is: Is this normal, or is this an indicator that there is a compression issue? Suggestions?

It's the oiler they have Oilers with a check valve to prevent the air when mounted on a cylinder. The oiler you have us probably meant for a bearing.

Hi Scott. If the engine has new rings, chances are they are not seated yet. Just running the engine wont set them, the engine has to be loaded to heat and force the rings to wear into the bore correctly. You probably could load the engine by holding a towel against the flywheel rims, making sure that they don't get too hot, or your hands don't get hung up in case the towel gets ripped out of your hands. It will take a while for the rings to seat. Ideally, the engine should be loaded so that it fires at least twice as fast as when under no load. The harder it has to work, the faster they will seat in. A check ball oiler may help, but was not original equipment for the Stover. Does the piston look wet when the engine is running? If not, you need more oil. Proper oil? SAE 30, 8 to 10 drips/minute is what you need. NO Multigrade oil.

Andrew: Thanks for the response. Yes the piston looks very wet when running, and after. I doubt the rings have been seated with load like you state. I will try that and see if it helps.
