CX Choke Revisited
I need to reopen the choke issue started by “badnova”. I, also, am having a problem with my 2005 CX.
This will be a little long, but want to include all I can. My CX sat for five (5) months and now it will only idle smoothly with the choke pulled ½ closed. It ran fine before putting in storage. It is searching with the governor without the choke. It runs fine above idle and at full speed without the choke. I thought something in the idle circuit. I pulled the spark plug and it looks like the engine is running very lean.
I noticed that the idle mixture screw had a stop on it and would only allow ¾ of a turn, which didn't help anything. I sawed the tab off and adjusting full in and out, doesn't change anything either. “Yes”, the restrictor bushing is in the air filter intake. If I hold the choke ¼ to ½ closed, the engine will idle fine, with no searching from the governor. However, the engine will NOT rev up with the choke. When I rev it up without the choke it runs fine and governor holds it steady.
I pulled the idle jet out and ran the engine without it in place. There was NO change in idle condition with or without it. I then removed the carb for cleaning. The float bowl had plenty of fuel in it. Idle jet has a #40 and main has a #90 on them. There was NO visible dirt in the float bowl. I used a spray can of carb cleaner thru all the holes and ports followed by compressed air. I checked the very small holes in the air-horn with tag wire and they are open. Reassembled, remounted carb and NO change to my problem.
I, too, noticed, like “badnova”, that the idle jet appears to have a plug in the carb end of the jet and holes on the sides of it. On closer inspection, with a magnifying glass, I can see a very small dimple in the center of the jet plug. The smallest wire I have is .015” and it will not go thru. So, is there a hole thru the plug or not?
Thank you, for any replies.

CX Choke Revisited
Thanks for the replies,
The good news is that it is now idling without the governor searching 
I pulled the carb again, removed all parts that I could and soaked the carb and parts in a vessel filled with Berrymans B12 fuel cleaner. I then agitated the mix with a low volume of air. Soaked overnight and agitated again. I did notice some dirt it the solution after cleaning. Blew all parts and holes with compressed air.
I can now adjust the low speed circuit screw and make it stumble in and out. I then took it for a ride at high speed (yea, don't race anyone) and all is well.
I will be draining the carb before next storage period and adding Stabilizer to the tank.
Thanks Again, Tom
