Hey AOMCI,

First time poster, but have loved digging through the forum for fantastic nuggets on how to get this motor going.

I feel like I’m very close to the finish line, but can’t quite cross it.  My 1957 Evinrude 18HP had been running for 3 seasons strong with only a water pump maintenance in between.  Come last year I noticed losing power at higher speeds and narrowed it down to the old pressurized fuel tank leaking.  Given the safety concerns of that I upgraded to a fuel pump (see attached pictures and a link to more).  I did a carb rebuild, as I was already digging into the fuel system. After doing that, I couldn’t get a strong spark on one cylinder so I did a rebuild coil/condensers/points on that and now am getting strong spark (.25 in gap using gap tester).  Come to today, I am able to get the motor to pop with a few hard pulls with choke out, some hisses with it half put in, then it did run for about 2-3 seconds and died, but after another hour of messing with it, I’m still at a lost.  Even let it air out for awhile, but still  can’t get it to run.  Below are a ton of pictures. I’m wondering if I have an issue with the new fuel pump.  When I prime, I’m able to get it to fill bowl and the bulb stays hard.  High speed knob is out a full turn, low speed is out 1.5 turns.  I’ve lock the throttle on the line on the throttle cam with the idle screw adjustment, because I noticed my throttle would reset back to stop in between pulls.

Any ideas would be greatly appreciated!
