616 ccka motor problem

[bigerico]

i have a 616 and it ran great i use it to grade my driveway a couple times a year with york rake. I started it and drove it out of my garage and it ran great as allways. i shut it down and started it again and it sounded funny and oil was pushing into exhust. i did a pressure test on cylinders it was 120 and 125 .the valves look ok thru the port i didnt pull the head because i dont know if i could find a head gasked

From what little info given, one might investigate a possible leaking fuel pump. Many time the fuel pump will let gas into the oil. Check to see if your oil is over the full mark. If your careful you can reuse the head gasket.
