A "compression test" isn't going to tell you if there's an air (vacuum) leak.

If you're certain the carburetor or intake manifold isn't the problem then you need to concentrate on the two crankshaft seals. I also agree that you need to reduce your oil content. Go to a 32:1 or 40:1 mix. Your engine will like you for it.
