Rodchester 2g, X3

BOY. 2G Been a hell of a long time. When "snapping" it should be well into the power valve, so the jets might not be that effective. How far off are they from a "stocker?"

What I'd do is try to get each one running separately, first. Any evidence of flooding "over" that is the floats sinking/ needles leaking/ too high? And you are sure it's rich and not lean? I guess it's not backfiring?
