Carb float question

[jjc839]

Leak free and brand new filters. I'm 99% sure it's fuel level. I'll update when the new floats are in. Everything is stock on the bike.

Runs good, hard to tell, bit of a stumble midrange. Stock size pilot and main, new.

Fuel level is still too high so I'm sure that has something to do with it. Will reassess with new floats. Plugs sooty.

a) plug gap. b) plug chop.

it's been long since I played with carbs but there really isnt much to fuck up.

new needles too?

mid range would be as vacuum is decreasing and it rolls off one jet to the next... drawing too much fuel... clip up.
hows your ign timing?

New plugs, heat range and gap as the manual says. New jets and needles. Timing checked, all good.

When I cranked up the float height, it basically got to where it wouldn't flood anymore, but it's by no means where it should be. I never tried to increase it any further. If it's still rich with the new floats I'll clip up. But it's set on the second groove as the manual states. I'll keep you informed.

Cheers

Ya well if I was smart I wouldn't be messing around with a 40 year old 125 now would I?

au contraire

If you haven't replaced it already, check that the emulsion tube isnt worn - specifically where the needle enters it. Fairly common problem on older high km bikes, the orifice gets ovalised causing a rich condition midrange

Especially Keihin's as they normally are not replacable, esp in the two strokes unlike a Mikuni.
Normally the only cure is a new carb or a fatter needle.
