Well, I bought my cl360 ('74?) and the guy said it had been sitting for "2 months" (which could be years) and wasn't running.
So... I cleaned out the old gas and put new gas into the clean tank,
checked the oil and replaced the battery. I spent sunday "cleaning" out the carbs, which were totally clean (apparently though some jackass had stripped the screw heads though), and found one of the reasons I can't start it.
The needle thing that hangs down from inside the carb was just laying in there and not screwed in like the other one. So i put it back where it was supposed to go.
After trying to start it for 10 minutes I finally get it going. It was backfiring a little. I rode it for about 15 mintues or more and
white smoke started coming from the carb area/under the gas tank/unidentifiable area. Then the engine didn't want to keep running on it's own (not without giving it some throttle), and I was tired and didn't want my bike to catch fire...so I put it away and promptly got sick with the flu.
I went back to try to start it again today though, and it is a no go.
I guess my next plan of action is to check the spark plugs (as it looks like there is a little bit of oil on the manifold on the right side) and see if they are still good.
Other than that, I am open to suggestions.
But it was running and lots of fun for like 15 minutes or so.

When you rebuilt the carbs did you:

- strip them completely and soak the body in carb claner?
- check all the proper factory settings with a manual like float height and air bleed screw?
- use new gaskets?
Did you clean and gap the plugs?
Check the points?
clean out the petcock?
Check the manifolds for cracks in the rubber?
Check to see that the battery was taking a charge?
What does the bottom of the gas tank look like?

I'm guessing that the white smoke you saw was from gas leaking out of the carbs somewhere.

2 months is not enough to turn a bike from running to not running unless you left it outside in the rain with the gas tank open and the plugs out.

These bikes need battery power to run and won't run under 2000 rpm unless the battery has a charge - if your charging system is not carging and you are running it down with the e-starter then it will have a hard time running.

BTW did you change the oil and fiter?

These 360s are finiky on the choke when it is cold - usually I start the GF's with the choke on and then quickly shut it off to let it idle and warm up.

no, i just kinda of sprayed them out and sprayed out the jets and stuff, they were so pristine it didn't look like it needed doing.

uhh... i am quite sure i didn't do that...
I found those settings in my manual ( 18.5/0.73 float bowl and 1 turn for the pilot screw) but i didn't even think to do it. i was just following the manual and it never said anything like that.

...no... :( they seemed okay, and honestly i was just trying to see if it was going to work at all.

no, i haven't done any of that yet. I got sick before i could keep working on it. the petcock flows nicely. the battery is new. gas tank is clean.

meaning i need to look around and see if i didn't put something on correctly? there are four tubes that come out of the carbs. two big and two small. the two big go to the petcock but i have no idea where the 2 small ones go. are they just drainage or something? my manual sucks, it doesnt say anything about it.

yeah, but i suspect the guy had a problem with it before hand, e.g. it stopped running and then he decided to sell.

not yet. the oil seemed passable and i was just trying to get it started.

i have been using the choke, and it sounds like it is Almost going to start and then won't.

Thanks so much for your feedback and advice. I have lots to do still it seems.

If they are actually as clean as you said they were then it should be ok.

Well I think that may be your biggest problem. The air bleed screws affect the idle, setting them up properly would probably get you close to a running idling bike. Keep in mind these bikes are somewhat cold natured and may not idle properly until fully warmed up. Also carbs are designed to leak when they get too full, that is what the float controls. If the float height is not set properly the carbs will leak as designed. Could be as slow as a drip or as fast as you or I take a piss. The manual should get you close.

They may be ok but I woudl check them for weep. Keep a rag handy and any place that looks wet dry it off. If it looks wet a few mintues later then replace the gasket.

Not completely sure what carbs are stock on your bike but if you are seeing two sets of upright nozzles one larger than the other the smaller one may be for vacuum. I don't have a manual in front of me for the 360 so the vacuum can either work the petcock, or it connects to the engine and works the cv slides. There should also be a nozzle on the bottom that the float bowl leaks fuel out of when it overfils.

May be a timing issue. Check the timing and points, most of the time when someone can't figure it out and lays up the bike it is electrical. Also these bikes are kinda known for bad or intermittent grounds so take a good look at all the contacts and clean any that look suspect.

Now it has started - you know it runs, time to do the preventative maintenance. Change the oil and run a magnet through it. See if there are any shavings you should be wary of. Inspect the filter too. Now would be a good time to switch to synthetic oil, My hondas love it.

New plugs are not just piece of mind they are a tuning tool. Learning how to read plugs is one of the great things about old vehicles that new EFI stuff has sent packing. YOu can learn a lot from a plug chop test as well as your old plugs. Also go to an auto parts store and get an inline plug tester - might as well see if those wires need help too.

Set the air bleed screws, give her two cranks of the throttle and hit the starter. it may just be that that is your problem with start up (with the air bleed screws closed you have no idle). Every bike has character and this includes start up procedures, you just need to figure out what your bike needs to run.

Also the needle you had to put back in, was it a primary jet or a slide needle? If it is a slide needle it should have different position markings and be shaped like an actual needle and held in by a circlip. Pay close attention to those markings as the needle height is important to your part throttle operation. If it is the primary jet or float needle you need to find out why it came out. It happens from time to time but it is better to pay close attention to make sure it is not striped in there.
