Give it to him straight, Doctor. He can't badmouth you for his own mistakes. (That is straight 10%-or-less ethanol fuel.)

My 2050 pioneer did that=: The verdict: The cylinder polished to a mirror. The second problem comes from the carburetor diaphragm -it let air mix with the fuel causing it to pump fuel on choke, but not on idle. = [1] Clean the entire carb in ammonia. [2] Check for cracks in the tank/body...

That is what I would do. Full disassembly, wear crackdown, and reassembly. = A good idea after reassembly is to check everything over, intake hose leaks are costly in time.

You could buy a gasket kit so you can cut as many as you need when they break.

That is the same as I do, only for a different reason.

The oil can also be coming from a loose oil line, bar, and a broken oil pump seal

I have a mark1 550 and the problem was the fuel. The 550 wants 50:1 or close to it - like Maintenance Chief said, this is a dealer repair (unless you have $400.00 lying around to buy the software)
