welcome to UHE pansie!

could you put your bike and location in your nik/signature please?

ok, sure the carb is beaten up and needs a real freshen up. i've serviced 2-3 lately and they were absolutely knackered inside. you can spend a lot of money on an old dell orto. i'm talking $200/£200 anytime in servicing and parts.

suggest you get a much younger carb or change everything inside. defo the atomiser and needle, smaller #52 choke jet with a fresh 'O' ring, fuel valve is £20, would renew the pilot if all greened up, new banjo filter...

etc etc and don't forget a good blow out and new 'O' ring on the fuel screw. when you look in the doc you'll see the mention of "the missing CD1 jet". look for this.

regards

Forever I had an idling problem on my 1997 FX600 and it drove me nuts. I could never get it to idle high enough even with the idle screw turned all the way in. I tried cutting the screw spring down and even removing the screw spring to get a little more slide lift. If I left the choke on it would help a little but not much. I finally saw a virtually new carb on e-bay and snagged it. When comparing my new carb to my original carb the problem became immediately apparent. The idle screw location was drilled and tapped a little off the mark causing the idle screw to have a limited amount of slide lift. Perhaps your carb was drilled wrong like mine.
