Bitter learning curve. Absolutely DONE with carburetors!!!

Have not torn it down, just drove it home tonight when this happened. I checked the oil and the level has not changed, but, when I wipe the dipstick there is clean new oil and a slight film of grey film on the white rag. I'm assuming this is the babbot from the bearings??
Also the oil pressure is low, 5 pounds at idle after warm, 23 at 2k rpms, 32 at 3k rpms.
