I did take fuel pump apart but I ran it on the lake afterwards and still had to pump the primer just like the last time. I did find that my primer bulb was bad on the new fuel line after I blew threw the check valve and air escaped the other side. Carb was cleaned before it was stored 18 years ago and when I got it, it was still in perfect shape. Replaced all the gaskets and Welch plugs anyway and it didn’t change anything. Main jet is clean as a whistle. Lead a from coils are only 4 inches long so not able to connect to wrong cylinders. I did. Or disconnect leads for ignition when removing armature. I disconnect ground and the linkage and just moved it aside. I took hose off the outlet to the fuel pump and tried starting the motor with the primer bulb hard to see how much fuel it was putting out and it wasn’t a lot. I have a fuel pump coming in Friday just to see how well a new one works since I robbed this one off another motor I have. I will throw a little mixture into the cylinders to see what it does next.
