OK fellows I posted a thread on here awhile ago about a 1979 XS650 pouring gas out the one carb. The general consensus was to re-build the carbs. OK did that. Also split the fuel lines and am running one fuel line from one petcock with 1/4" I.D. line. New problem. The bike won't start. Spray starting fluid into the cylinders and turn it over and nothing. Not a putt. Bought new plugs and still nothing. Hold the plugs against the cylinder header and turn it over and, well, really I can get more spark by skipping stones off the road. Can anyone tell me if these 650's just don't make the kind of spark you get from automotive plugs or V twin plugs or are they good firing electrically and I just have another problem. Spark also seems to be intermittent on the left side, but I see that's a common problem on here.
