Hello All,

I have a been trying to get my 57 Evinrude 7.5 to run, I had it started but it only runs for a short while and dies, it would not stay at idle speed either it would run very choppy then die.

I changed the spark plugs due to oil being on the plugs and the gap was off so I re-gapped them at .030. Rebuilt the fly wheel and replaced the spring.

Now the motor will not even turn at all. I have taken the carb apart, when doing that I took the high speed knob out and the low speed knob out, a lot of oil and gas came out holes, why is this?? And why is there oil on the plugs.

The other issue I have is this motor did not come with a pressurized fuel tank, CAN THIS MOTOR RUN WITHOUT ONE??? I do not think the 57 7.5 has a fuel pump does it? If I need one where do I get one or can I put a fuel pump on.

Please, I need some good advice, I thank you in advance.

-Rich
