How's it going

Today rode my CB360 around my neighborhood, then the egine started bogging down until it finally died. Thought it would be low gas, so switched it to reserve, tried to kick it again, and would run for alittle, then bog down again and die 5 feet later. Kicked it two more times, both times making a small popping sound. So I walked the bike home.
Decided to try again, kicked, fired, was able to almost ride to the gas station, but very weak, and evetually died. Walked the bike the rest of the way, filled it with 87 octane (which I believe is what I filled with before, only second fill up since getting her running), tried to start it, but same results as before... Felt terrible, bogged down, died.... Now I cant get it to start at all.
What could have caused this? Would a different octane affect it at all?

Whenever I kick it now it just makes a "squeezing pop" sound out of what i believe to be the carbs.

Info on bike - 75 360t, ran perfectly before today. Kick start only. Fuel lines are clear, so can see fuel is getting through the petcock fine. Battery has good charge.

Thank you
 
Your going to have to check battery voltage although it sounds like your not using electric starter
It may be flooded, what position is the choke lever, they tend to vibrate ON sometimes (particularly if the 'lock' tab is bent, loose or weak)
 
Battery is at 12.8V
The carb bowls may be flooded? I tried kicking it with the choke on and off today and both had similar results: none...
How would I check/remedy the flooded carbs?

Thanks PJ
 
Fill 'er up with 91 octane man, she deserves the best! I don't think I've ever experienced any worse performance from 87, but it just makes me feel better filling up with 91. It's not like CB360s guzzle gas either
 
I was going to! but I went in to buy ciggs and had my roommate** fill up for me, and forgot to tell him to do 91...

**he wasnt riding bitch, skated behind me ;)
 
Battery sounds good at 12.8
Stock 360 runs better on 89oct
Flooded means the plugs are wet, have you taken them out?
What air filters are on it?
 
haven't been able to take the plugs out, had my ratchets disappear a couple days ago... heading to the swap meet tomorrow to find replacements...
What should I do if they are flooded? What causes it?

Air filters are the exact ones posted in the thread you posted recently, unfortunately... emgo
stock mufflers
 
OK, take a look at the 'cheap filters' thread I started
http://www.dotheton.com/forum/index.php?topic=45863.0
It will give you some points to check
Plugs get wet when there is too much fuel or not enough air.
If you haven't jetted properly it's easy to break things (although this was an air leak AND timing issue)

Click to expand...

The best fuel is the fuel that is required, not some perceived benefit from so-called "premium" fuel. Premium fuel is not better fuel, it is just more resistant to detonation. If you don't need it, you are wasting money on a fuel that burns slower and will give you LESS performance.
 
Even though you checked that you are getting fuel flow through the petcocks, it still sounds to me like the carburetors are not filling with fuel. Your float needle valves could be clogged. I would start there.
 
Opened up the carbs, when through all the jets... all seem clear... put it back together, still nothing.
Definitely gettig gas in the bowls
 
Plugs are standard 13/16", have you pulled them yet?
If your getting fuel, it's either ignition or mechanical
 
Small up date, white powder on left spark plug where it connects to the wire (still havent been able to get the plugs out, need to pick up some tools)
 
That's oxidation or plastic dust?
New plug caps could be a good idea
 
Oxidation, seemingly...

So forced my ass to home depot and picked up some ratchets... Spark plugs are completely black, running rich?
And they seemed a little wet... If there's any moisture at all is that an indication of flooded carbs? Or do they have to be obviously wet...
If it is flooded, what should I do?

Thanks so much for the help so far PJ and everyone else

edit - Whats plugs do you reccommend for the 360 PJ? Going to head to autozone in a little bit to replace em
 
Turn of gas, can you keep bike under cover overnight (I don't know if you have garage?)
Leaving plugs out will allow most of the fuel to evaporate, kicking it over several times with plugs out will help (ignition off)
either get new plugs or 'cook' the ones you have( a lighter or matches WILL NOT WORK)
I've left them on hotplate or over gas burner on high until they dry out/burn clean (when I lived on my own and didn't have propane torch or Oxy/acetelene ;D )
Really sounds like you flooded carbs
 
Picked up new plugs, and did as you said, leaving em out...

Checked spark though (connected plugs to wires and pressed the tip against the engine and kicked, ignition on) and saw no spark... Am I doing something wrong? I'm going to recheck the wiring and try again tomorrow... Also, can I check the coils by taking the points cover off and kicking until the points gap? Should it spark?

Thanks
 
You can just flick points open if they are closed.
If gasket is missing points can ground out on cover, the fit is a 'bit tight' ;)
 
Ok, im getting 12V at the coils, but no spark when I ground the plugs to the engine. I took off the points cover and had a buddy kick, and no spark over the points after kicking a few times... Bad coils? How do coils go bad? and what does it mean if both go bad at the same time?

Thanks
 
Im a fuckin idiot,..
switched over to my old battery, fired right up on both cylinders...
Both batteries read >12.5V though, so somethings up with my newer one

Someone lock and bury this embarassing thread
Thanks everyone for putting up with me
