+1I'll let it set for a few days, then start, and run it. At least then, the MMO will be able to mix with the oil, and circulate through the engine.
Best thing you can do for any internal combustion engine is keep the oil clean. Change it as often as necessary, even more so when bring one back from neglect. Oil's cheaper than anything else you'll do to keep it running.As of now the plan is to run it a few more days, then change the oil, and filter.
