Sticking choke plunger

Ok all, quick and hopefully easy question :

I have a sticky choke plunger, on the left side, and I am wondering if anyone out there has any kind of quick and dirty remedy? My thought was to just see if I can't get some WD-40 or some other lubricant on it using the handy dandy long straw that comes with it to get it right in that tight spot.

I want to make sure that it won't cause any unforeseen issues before I do it though. Currently, I just take a key or little screwdriver and 'manually' push it back in any time I use the choke. But when it gets cold(er) this winter, that is going to be a real pain.

Any thoughts/ideas/revelations are appreciated

No advice on this at all? Not even a "Yeah, of course that's what you should do dummy!"

C'mon now - if the question is that dumb, SURELY one of you should have jumped on it ; ) Or perhaps no one else out there has ever experienced this, which would seem a little hard to believe, but I guess stranger things have happened.

Never had the problem, but recently learned that WD-40 leaves a residue that over time gets sticky. So if you decide to lube the plunger, might want to use something else.

I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!

Mine does this sometimes. I just lean down and push it back in with my finger. I recently sprayed a little light penetrating oil on the plunger and it improved quite a bit.

I'd spay it with cable lube.... If you have some in the spray can.

Carb cleaner followed by white lithium grease in the spray can.

Shouldn't the choke lever/cable be pulling it up and down ?
