Oil on plugs
Hey everyone,
I was out fishing today with my 4 stroke Mercury 9.9hp motor. It was giving me some attitude, and wouldn't run for longer than 4-5 min before dieing. I brought it home and went through the fuel lines and inline filter and it was plugged! Barely any fuel would've gotten through. So I cleaned it all out, it was rotted tube from inside the fuel tank where it sucks it up and out to motor. My worry is did it do anything to my motor? I pulled the plugs and attached pics of them below. They are old plugs that should of been changed awhile ago. But I'm worried that there was so much oil present on the plugs, is that normal? Do I have bigger problems? Also when I was "milking" her back to the ramp I had to partially choke it, would that cause this on the plugs? Thanks for any input!
