I wouldn't worry that much about it. It doesn't really matter what the oil level is after an engine has been running for 45 minutes and then shut off for 45 minutes or even two hours. All that really matters is that it's in the safe operating rangeand not too high above the full mark before you start it. I would assume oil expands a little bit when it gets warm but probably not over a couple of millimeters on the stick.Went out this morning. There is still no carburetor hooked up. Gas tank is removed (attached to carb doing my own little test, which is showing no signs of leakage btw).
oil is almost 1/2" past full... yesterday it was perfect.
wiped it off, put it back down in. screwed it in slowly, waited a min, screwed it out slowly. Oil level had fallen almost 1/2" (still a little above 'full').
decided to see if spinning the dipstick fast to pull it out would increase the reading. still the same level.
running out of ideas here. I'm debating pulling off the dipstick tube and monitoring the oil level in the hole. if no one has any ideas, i'm just gonna wrap this up and chalk it up to something weird and i'm just getting false readings. Carb isn't leaking (i have the tank up real high and the carb sitting on someting where i can see any water leaking out. Unless it matters whether the engine is running or not, i don't know that much.
I am confused about the statement about the tank being high up where you can see any water leaking out. Don't know why that would be any water in this situation
