    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

this bike is a 1981 with about 22k on it for miles. i have worked really hard on getting my carbs to work right, but no sucesses. my carbs were working well when i got the bike and then gradually i felt them starting to fail. when i start the bike let it run for a bit and then shut off the bike i feel the pipes and find that one is not hot. the one that is not hot is (when looking at the bike from the front) is the second from the right. so that carb must not be working. we will call this the number two carb for clarity. this appears to be the main carb, becuase the fuel line runs into it. i have had the carbs of 5 times or more and cleaned it well every time ,soaked them a couple times overnight and still nothing. i have ran seafoam still nothing. i have put a new seat and needle in the number two carb. after i did that something funny happened. i started it for 1 min and then shut off cause the bike was not running right and found that that number two carb was the only one running. then i started it back up again and after ahile the other three started working, but then the number two stopped. it really seem like the gas is just flowing through the carb. there is gas mixing with the oil (i think just because of the huge gas flow) and also thre is white smoke, and also a little gas comming out of the exhaust. this bike has four carbs to one exhaust. i am really confused to what to do next. if anybody has some suggestions to what to do, it would be appreciated.
if you have anymore questions about the bike just ask.
and also if i was just to put new set of carbs on my bike, what types are compatible. (year, bike cc's etc.)

thanks alot,

blake

The petcock vacuum comes from the #2 carb and when the petcock diaphram goes bad it sucks fuel through it. Is the #2 spark plug fuel fouled?
 
Take off the vacuum line to the petcock and see if it has fuel in it. If so order another petcock and meanwhile run it on prime and plug the vauum hose.
