I have recently replaced the head gasket and converted to solid sate ignition. It cranked right up after completing this repair. Ran it around the yard and it worked fine. Then it died. Would not crank. Waited a few days and it started and ran. This pattern went on a couple of more times. Now it will not start at all. Will almost start and backfire. Rebuilt the carburetor , no change. Have tested for spark and we have that, appear to have fuel - because fuel comes out of bottom of the carb. Need to check the vacuum on the carb next. Any other thoughts on what could be wrong.
