    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...

  • Returning Visitors

    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.

Time to explore correct petcock function. start by making sure no gas flows from petcock when in "on" or "res" spot when engine is off.

1981 suzuli gas problem

thanks guys i pulled plugs only one seemed wet and will chech the petcock later today and will let u know thanks again
 
was it the #2 plug(second from the left ) that was wet?? My 650L had a torn petcock diaphragm and was sucking gas through the vacuum hose in to the number 2 carb and making the plug in that cylinder wet. It was also putting some liquid substance out the left side pipe.

That's exactly what my 650 did last summer!
 
i think it was the second if not it was the first one on left
 
check the petcock first thing. Odds are the diaphragm has a hole in it allowing gas to go through the vacuum hose in that #2 carb
