    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.

I rebuilt my carbs which were running very rich when I first bought the bike. I found the previous owner had set the float hights wrongly and this cured the problem. All except number 4 which is still running very rich. Mixture screw adjustment had no effect.
When I removed the carbs again to re-check no 4 I noticed I had not seated the the diaphram in the locating lobe properly. This would have affected the the seal on the diaphragm.
Would this have accounted for the rich no4 pot?

I don't want to reasemble until I get some feedback.
 
Yes it could have, The only way to find out is put it together and try it
 
reasembled the carbs tonight but no joy. The numer 4 down pipe is noticably cooler than the rest. I,m going to replace the float valve as I suspect this may be the problem but I would welcome other theories.

The UK dealer wants ?24 ($50) for one float valve and housing!!! There is no way I'm paying that price. Can anyone recomend a cheep supplier of carb overhaul kits. I don't mind shopping outside of the UK.
 
If you think it is the float valve WHY not swap between one of the other carbs. But I think you need to clean that carb again
