This 1976[date of manufacture on front fork] KZ650 is starting to frey 'me' nerves. I recently replaced the cyl. head c/w new gasket,new points and condensers with the hope of at least some type of idle speed. It will start every time you spray a small amt. of gas in the carb intakes, burn it and die out. Sometimes it will keep running for 10 to 15secs. with the choke almost on, or alternating your hand over the carb intakes. It seems to me the clys.are starving for gas,or I have a vacuum leak. I see on this site members talking about vacuum hoses, but I can't see any place on the carbs for a hose connection, only the four small ones on the bottom of each carb. I do notice the fuel line from the tank,going into a tee and then into the carbs is loose,move forward and back, but no gas leak is visable there. I set the four screws on the bottom of the carbs two and half turns. Is this correct? Any advice sure appreciated. O ME NERVES! Newfie saying!
