You're right...not really loading it. As for volume:
-I changed the oil 10 days ago when I changed the fuel pump, and the crankcase showed dead on the full line when done. I had drained it completely prior to that and DID NOT refill the oil filter or put in a new oil filter.
-On Sunday morning, I checked the oil and it again smelled of solvent. But, the level was still at the full line, or just a hair above. Test warm-up but only for ten or so minutes.
-On Monday afternoon, drove it for about ten minutes and warmed up more after that. Ran just fine (even on the very steep hills that I used while chasing the condenser gremlin).
-Checked the oil after letting it cool for twenty minutes. Oil cannister is now filled with VERY thin (but clear) oil, and crankcase reads above the full line by about 3/16 inch.
Still very cold temps here, but it seems obvious I have something more than a bad mixture setting going on. I don't understand why it's not running poorly. Only thing I can think of is I just don't run it long periods. Glad I didn't too, because I am worried about the engine internals getting washed down.
SWEET is definitely bringing his good spare carb over this weekend, so I have a few procedures to go through. Our plan is to check compression first, then, if good, swap the carb and fuel filters again.
Thanks for the ideas. Keep 'em coming!
