Hi Jack � I�ve disassembled both my carbs and found a few things � 1. That little piece of rubber that goes on top (if you�re looking at it from the bottom of the carb) of the slow jet (I think it is the slow jet) is almost broken into 2 pieces on the right carb.

Maybe this would explain the difficulty in idling. On the left carb, it looks fine.http://www.siriusconinc.com/pro-detail.php?pid=&product_id=1056Consider this, if your float bowl seals are getting hard and dry also:http://www.siriusconinc.com/pro-detail.php?pid=&product_id=5286

2. On the left carb, I can�t remove the float valve thingy. Any ideas on how to get that thing out of there. I�ve tried grabbing it with needle nose pliers but it won�t come loose no matter what, and so I can�t check the condition of the O ring that�s down in there around it. Seems to be frozen solid. It came out easily on the right carb. How bad is it if I can�t get it out?A finishing nail and small hammer should send it through.Once cleared of the path, sand to make clearance for the next usage.

3. Everything looks generally fairly dirty inside the carb. Lots of deposits in there. I don�t get the feeling it�s actually been cleaned recently, although my experience is limited, oh jedi-master.Is the tank a POR-15 lined tank?

4. The diaphragm (?) thing that�s attached to a piston thing with a spring in it seems really worn � very loose � but I don�t see any tears in it. Is that ok?No tears is a good sign.The first sign of wear is usually a defined "folding" crease when transiting from idle to WOT.Lift the slide with the diaphragm in place and look for points where the rubber folds at a crease.

5. I should probably replace all the jets and o rings I can while I�m in there, but I�m kind of bewildered on what kit or kits to buy to do this. I�ve looked at the parts that are available on this page: http://www.bikebandit.com/houseofmotorcycles/1970-honda-scrambler-350-cl350k2/o/m151898#sch395480. Not sure what to get there, if anything. I�ve also looked at your sponsor�s SCI website, using the link you gave me earlier, and am getting lost.Unless the jets are the wrong size, there's no need to change them.The o-rings, if not supple and sealing the gaps NEED to be changed.These are the best kept secrets on the SCI web page:http://www.siriusconinc.com/pro-detail.php?pid=&product_id=3999These o-rings work on both the main and mid jets.You need four for a complete carb pair replacement.That leave you with four more replacements plus a spare.And, that's at less than the cost of three jets. You do the math!

The suggestions above cost almost nothing, in the grand scheme of things.While you're shopping, check out the other CB350/CL350 items available to amortize the $12.50 fixed shipping costhttp://www.siriusconinc.com/search_result.php?make=1&model=cb350&part=All&partno=&x=29&y=21&search=search

Any help you can offer will of course be much appreciated. I think I owe you at least another six-pack by now. Maybe a keg.If you're willing to share it with me, a 12 pack would do nicely.I bet we could solve all the problems of the world in one 12 pack.Pack a bag, in case you need to use the futon in the basement.Old guy like us don't get enough story telling events like that at our age.

Thanks! Slow Jet #38: KHS-120038
