Re: '74 CB 360 Cafe Build - Boomerang
Rechecked valve clearances, re-set timing (was slightly off). Double checked carbs.
6-8 kicks, choke open, nothing.
2 kicks full throttle, nothing.
Pulled the plugs and they're dry. Last time I removed the carbs there was fuel on the intake manifolds. Intake/exhaust valves are opening/lifting as normal

Arrrgh, I hate motorcycles.
just crack the drain screws on bottom of carbs for a second and make sure they got gas in them from petcock.
And you pulled plugs and cranked her to see you actually get spark to them? not fouled, points cover not grounding...

Coils wired correctly? Blues and yellows. Black to + blue and yellow to - and all that?
With my aftermarket coils I wired them backwards once. blue & Yellow to + and blacks to -. It fired and idled fine. but would cut out and die w rpms. That was a head scratcher for a couple moments.

The "keeper" pin in the camshaft that traps advancer. Ummm...
Dude I am running out of ideas. Thats what pisses me off about this whole internet thing. I wish I was standing there scratching my head and staring at it with you.
Choke the shit out of it and crank her. Its got to be getting gas.
Have you checked compression? w a gauge?

At least y'all have some ideas for me. I ran out a while back. Petcock is working, I don't have much gas in the tank so I swapped it out with a bottle, so bowls were full up.
I have the carbs out again, gonna recheck the pilot circuits again. It's like some fuel is getting to the intake valve, but not enough to fill up the chamber to make boom.
I haven't checked compression with gauge. May have to get one if I don't make any progress.

Pull the A/F mix adj needles out. prop the butterfly open I use a 10mm socket. shove the carb cleaner tube in the needle hole, move the angle of tube around as you spray. Besides squirting out the single large A/F mix hole You, should see 3 tiny little fountains under the butterfly. I might have a picture I took.

Re: '74 CB 360 Cafe Build - Boomerang
I think??? But even if clogged it ought to pop off on the larger air/fuel circuit alone. It will hesitate on take off if the 3 pilot holes are clogged.
I use a tiny bent safety pin to poke in those 3 holes to clear them.

Re: '74 CB 360 Cafe Build - Boomerang
I luvs teaching people new stuff ;D
Those butterfly screws are really chewed up
It's not unusual for the 'reservoir' under the bypass holes to be slightly gummed but most likely you have something wrong with shut off valves and/or float level

Re: '74 CB 360 Cafe Build - Boomerang
HA those are an old pair of "parts carbs" everybody who sees that pic comments on those screws. LOL
I hate it on the internet...I wish I was just there so I could get my hands on her AND screw it up myself.
I told him float level earlier he said its at 20...thats good for starting.
told him to crack drains...he did and said bowls are full.

Re: '74 CB 360 Cafe Build - Boomerang
LOLZ, ;D
I think you know I have ton of carb pics in various stages of 'destruction' and repair.
Anyone interested can search for Photobucket and maybe youTube links, pretty sure I've posted them multiple times?

Re: '74 CB 360 Cafe Build - Boomerang
Shut off valves are working fine. I still have the carbs off, will recheck float height.
Also is there anywhere to get formed gaskets for these carbs? I have generic round o-rings and I have to fuck with them every time I put the bowls on.

Re: '74 CB 360 Cafe Build - Boomerang
OMG I know I fucking hated those O-rings !!!
Honda sells the gaskets...but they are $16 each...AND I dont know...They may just be O-rings too. When ordering, I would tell the parts guy...If I get these and they are O-rings Im gonna shove them down your throat. And make sure you can get your money back If they are not CORRECT FACTORY SQUARE GASKETS. Before you order them.
BUT I bet they are perfect and correct.

Yeah going to have to go to the dealer, these o-rings add too much frustration to working on these carbs.
Poked out and blew carb cleaner through the pilot holes on both carbs. Clear. Going to throw them back on. I'm 100% convinced these carbs should start the bike at this point.
I'll double check spark, etc when I get em back on.
Ok maybe more like 90%. I'll be 100% when it starts

Re: '74 CB 360 Cafe Build - Boomerang
Brendon at Common Motor Collective has the correct 'O' rings.
Use a TINY dab of contact cement at the 5 'corners, press 'O' ring into position then let it pop out until glue 'dries'
re-fit and your done. (it's easier than the Shellac Kei-Hin/Honda used at factory)

Floats are at 18.5mm as per service manual specs
I got these round o-rings from Brenden/CMC actually. Maybe they changed supplier.

Will do - been using masking tape and pulling it out when bowls fitted

Ok, now I'm just getting pissed off.
Sparking fine. Carbs have been gone through 10 times. I'm still not getting a pop.
Neutral, no clutch for kickstart, correct?
Kicking the crap out of her. There should be fuel on the plugs when I pull them, no? They're still dry. Argh.

Re: '74 CB 360 Cafe Build - Boomerang
Possibly float. Spark plugs should not be wet with fuel or that would indicate flooding.
