    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.

Need help with a non-Suzuki carb

I'm rebuilding a carburetor for a 1979 Honda XR250, and can't find diddly squat for the thing, right now I really need the spec for the float height. It's a Keihin carb, not sure of the exact model. There's also only 1 adjustment screw, #7 in the picture. Can't figure out what it should be set at, got it at 1.5 right now.

I've been googling for hours it seems, can't find anything :( its not for my bike, i'll ask him if he'll buy a book for it, I thought somewhere on the internet I could find float level specs for this thing, guess not!
 
Give Honda a call. 866-784-1870. I know Suzuki will photocopy and email you a service manual if you ask them, maybe Honda will too.
 
i can check my book tomorrow if you want , no7 is usually 1.5 out from closed, dont use a k&L rebuild kit there junk!, check the shaft to see if air gets past the old packing if it does it will idle irraticly
 
On my 74 xl350 with similar carb, I set it at 1 to 1.5 turns out. Beware the o-ring at carb spigot/cylinder head interface-after 32 years it may be tired and causing a hanging/erratic idle.
 
Thanks for the replies! I'll tell him to check that o-ring, wouldn't surprise me if it's bad.

PM sent Platinum2!
