6x4 oil in carb

I have an older 6x4 gator that just recently started to run bad. I cleaned the carb out and still nothing. It runs great for about 5-10 minutes then starts to sputter and smoke. I went to clean the carb out again when I noticed oil inside the carb. I believe that the oil is the reason why it’s running so rough.

From the research I have done it could be a bad head gasket. I compression tested each cylinder and they both got up to a little over 150psi. I’ll try a leakdown test tomorrow and see if each cylinder holds air.

Any help/solutions to this problem would be greatly appreciated.

Thanks!!
