My 79 kohler 14 hp is burning oil at what I think is an alarming rate. Dipstick showed full and I mowed, about an hour of run time. Checked after and it was just under 3/4. After next mow, it was 1/4. I just filled and am ready to mow. I think this warrants some attention and likely rebuild or rings???. Fairly certain this is a standard and never been bored.
Just got back in from mowing and spraying! On startup, a large cloud of white smoke for quite some time. That kind of goes away, though I see white smoke often while mowing. Using 30 weight, last breather change... hmmmm. I’m going to guess 1985? If then. Could be orig. No visible oil leaks, though I haven’t gone over with a fine tooth comb yet. I’m going to pull the head at some point and see what I can see.
in the overall scheme of things, how bad is 1/4 of the oil being burned with an hour and change of run time?

That more then I'd like to see.
I'll bet others will be by and have other ideas.
I f you rebuild your motor you will be surprised how much more power you'll have
Maybe a decarb will help or try some gas additive.
Let’s see... 2020-1979 = 41 years of an engine running virtually untouched. I do not recall this engine being rebuilt ever. I guess I’ll find out when I pull the head. Seems my father got his money’s worth on this engine. It does seem to lack the power I think it should have. Mowing semi tall grass bogs it down. I guess it’s time...
