I have a fuel / oil mix coming out the small hole just above the prop when i pump the bulb. Does anyone think it could be the diaphram in the in the fuel pump?

Thanks, I'm trying to get the pump apart but of course I have one screw that dosen't want to cooperate.

Finally got it broken down, I don't really see anything visually wrong with it, could it be the reed valve?

Fuel could be leaking into the cylinders on the pulse side of the fuel pumps.
No on the reed valves
