74 CB360 help

[Luck]

First post so please forgive me if this is in the wrong area. I recently acquired a 74 CB360. Bike has been sitting for 10+ years. It has 90 percent of the parts but some are most definitely going to need replacement. Im not looking to make it faster, Just clean and fun.
I grew up with two stroke snowmobiles and motorcycles and Im not afraid to admit that I know squat about 4 strokes. I can do most anything I need to, but knowledge is what Im here seeking. To begin My carbs appear to be almost shot. I have never seen anything quite so filthy. I tore them apart sprayed tons of carb cleaner into them and heated them slightly in order to remove the slides. The diaphragms were shot, so I have them coming now. Any help there would be most helpful. I also ordered a new carb kit for each carb. My concern with the carbs is how do I know that I have gotten all of the tubes and openings cleaned out completely before installing the new jets, etc? I have heard lemon juice, naval jelly, acetone, and my friend recommended Evinrude Tune up spray. Its really aggressive for cleaning or decarbing boat engines. Anyway, I want to soak it in the best chemical I can find so I can feel safe knowing that its actually clean when I put it back together. Whew! Next question, has anyone ever tried to clean out a tank that has been treated or coated in some sort of white crap on the inside? I can see rust but combined with this garbage it just doesn't look good. I bought Naval jelly. Anyone think this might work to remove all of this crap plus the rust? Finally, I need one float for a carb and I don't want to spend 40.00 for it. Is there a board sponsor or used parts dealer that may carry something like this. This is it for now but I will be back tonight! Thank you for having me.

The stuff in the tank is probably 'Kreme' sealer, if it isn't loose or leaking leave it alone
Carbs are rarely 'shot' unless they are physically damaged with broken off parts.
If slides are not damaged you can get diaphragms from JBM Industries

Yep, I ordered a set of them. I have a quick question. What have people been using to really clean the carb out? Something I can soak it in and walk away. I have it looking waayy better than it was but Im still leary about leaving gunk behind. I have read about all the naval jellys, carb cleaners, etc. What has worked with great results? Will the varnish (whats left) wear away from new fuel being run through?
I ordered the K&L carb kits and I didn't notice the bowl gasket in there. Does the big o-ring fit in its place?
I really don't like the sealer in the tank so Im on the lookout for a new one. let me know if anyone has a tank laying around. I do a little custom painting so Im ready to spray something.

Damn, Luck, you're living up to your name, your first response is from THE baby CB guru.

Kreme is pretty low grade as far as tank linings go. Gasoline will peel it off, eventually, but until then, reline or swap tanks with a decent one. Evinrude tune up spray is just repackaged SeaFoam, more gimmick than anything else, it can help if the carb is slightly dirty, but if the jets are green, forget it. Complete rebuild kit after soaking in a bucket of Berryman or similar real deal, banned in CA and New England carb dip.

Plastic floats can be fixed about 70% of the time with high heat, like a red hot needle to soften the plastic and melt any cracks/pinholes back solid. Brass floats can be soldered, but don't be surprised when you hit it with heat and it takes off like a small rocket... Foam or lacquered cork/balsa floats need straight up replacement.

What have people been using to really clean the carb out? Something I can soak it in and walk away.

Gunk makes a gallon container of solution called "carb dip" with a tray inside. It works well for really gummed up carbs but it must be disassembled. Plastic/rubber won't survive long in it and since there's no pressure/movement, etc, you won't get it totally clean.

Dip it overnight then spray all the passages with carb cleaner until you get a steady stream out the other side of the passage. Also, I pull a wire out of a scale brush (for welding) and stick it in the end of a dowel rod to make a tool for cleaning out tiny passages in jets and whatnot.

If a couple of dips doesn't cut it, you'll have to do something more extreme like the lemon juice+water on a barbecue grill thing.

Thank you, I did read about that. Im not sure that's not going to be necessary, just trying to cover my bases before I move on and install the carbs. Anyone know about the bowl gasket in the K&L kit? Im wondering if I will need to order the actual gaskets if they are available.

Carb dip works great for mechanical slide carbs but screws up CV carbs
The seals on throttle shafts will either dissolve or break up so it isn't a good idea to soak CV's
To make them look 'pretty' use DIY soda blaster
