Need help with a non-Suzuki carb

[musicman]

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.

Just try using Google search & ask your question

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!
