HELP! Barely runs now...carb cleaning on the bike and re-installing airbox questions

I have tried to read all 17 pages of carb threads and as much info as i can digest from the "verses". I could not find this discussed. When I shot carb cleaner into the back carb drain screw opening while stoping remaining part of opening the cleaner backed up all the way up and out of the vent houses and fuel intake line. However nothing came out the drain on the bottom of the carb. when I did the same to the front carb (shot cleaner into the screw opening cleaner ran out of the dran but did not shoot out the vent or fuel intake line. My question: is the drain on the rear carb stopped up? or is the drain on the front carb open and should be plugged?

Also, the PO had removed the "air cleaners" trying to get the bike to run. I have gathered the necessary stock ears, airbox ect. I have plugged the reed valves, put tubing and t on the carb vents to reach the right air box, and put a hose on the crank vent. I think I am ready to try to re install the stock airbox. Question 2: can I put this airbox in with out pulling the engine and my remaining hair out? Give me advise please. thanks. jmczzz

Dunno bout he airbox, And yes, something on your carb is plugged.

degoated, Eared
stripped, lowered, raked, bobbed,
reed valve boxes shaved
ported and polished
balanced
right side dump exhaust
heads and cylinders shaved for compression
looking for smoothbore sidedraft carbs
possibly fat bob tanks

What Duck said- that one carb is plugged.

If you're referring to that "airbox" that is just above the engine, running from front to back, I don't know how you'd get it back in without at least pulling out more hair.... I don't know if it could be done if all the stuff around it was removed. I would guess it could be without pulling the engine, but you know how those pesky engineers can be.

Gotta love those butcher PO's too; I'd have liked to seen him getting it out.

Good luck with it, hopefully someone who has "been there, done that" will jump in...

Correction, I think.... I was just browsing the Verses and the following two sentences jumped out at me, and make me think that, No, you can't get it back in without pulling the engine, though I'm not certain. Here's the two quotes that make me think that- (this is regarding doing the "ear shave")-


Quote:
It has disadvantages, like it is permanent unless you pull the engine to put everything back.

Quote:
The worst part was getting the air box out (had to cut it into pieces)...
Just came across this one too-

Quote:
The only way to pull the airbox without cutting it out is to remove the engine IIRC.
Sure seems like you may just have to bite the bullet, commit to the job and yank the engine...

You may not need to pull the engine if you do it on a hot day or warm up the air box so it's more flexible you just might be able to get it back in.

Or just leave it shaved... a little more power... mild (claimed - I haven't seen one) loss of MPG, many think better looks....

thanks, duck, doug, dt.
to I think duck means the carb that did not drain out the bottom drain plug. I will try to work on that drain softly with a probe wire. If that doesn't open something up then I guess the carb must come off and be rebuilt.
Question 3: is there such a thing as a rebuild kit like can be had for a auto/truck carb? I even got a rebuild kit for my 52 fergerson tractor. but I don't see one listed on the Kaw site parts?

No, there isn't any kits for these Carbs. I just went thru that whole thing myself not too long ago.

Got to buy the stuff individually.

and oh yea curtis, shaved may be the only option. but I didn't want to lose any MPG or have to re jet.
BTW question 4: how can I tell what jets are in the carbs now? I doubt the PO butcher did a re jet, but how to know for sure?
