And of course the jets on these things are mundo finicky. If you haven't disassembled the carb yet, do so and clean it out, making sure you get the jets and the fuel feeder screw from the bottom of the bowl. Also good to check the float to see if it's opening up the incoming fuel jet.

Mine had sat for a few years, and it varnished to the point where the bowl had flakes in it, and this plugged the jets twice before I got it cleaned out (wire brush). And of course, something in the lines blocked the jet that feeds fuel into the carb.

However, the issue is feed - also check the vacuum line going to the pump - these things get old and brittle and can lose suction (I had to do this too). Also a good idea to take off the fuel pump and do a finger test of the diaphragm to ensure that there are no cracks in it that you can't see, but can feel.

And after doing all this, I'm guessing that the main culprit is the crank seals.....
