Motorcycle Repair: Honda CMX450 rebel, fuel enrichment, compression test

Question
Rich,
I've got an 86 cmx450 rebel that will start no problem in the mid-day when it's hot in my garage, I can't get it to start cold at all. I've ran a compression test and both cylinders are within range. I also pulled the carbs and cleaned them. I can see the 2 actuators going down in to the carbs when I pull the choke lever, but the butterflies do not move. I would appreciate any info you can give me.
Thanks

Answer
Those carbs don't have a traditional choke plates.  It uses a fuel enrichment circuit to add fuel after the throttle plates. The choke cable lifts a plunger in each carb that opens a fuel passage dumping more fuel into the intake.  There's a fuel circuit in the float bowls for the choke circuit separate from the idle and main jet, that is probably still plugged.  You may have to soak the carbs in a good cleaner to make sure the passages are clean.  I ususlly run a very small wire into those jets to make sure they are clear.  Just be sure you remove every o-ring and rubber part or it will swell up 3-4 times it's normal size.
