So I changed out the stator, trigger, switchbox, rectifier today. I have new plug and wires, I 1 new coil. Engine still wont start. I popped which was exciting. But can't get it to repeat this. I have new gas line, cleaned carbs, have consistant spark at all four cylinders, timing looks good. I am thinking I most have a fuel problem. what might cause a problem in the fuel system? I checked the bowl settings, needle valeve,cleaned em up. I am thinking fuel might not be getting to the cylinders. What is on the other side of the carbs between them and the cylinders? Anything that would possible cause gas to not move through? Thanks
