The Honda carb manual doesn't exactly cover the bastards they installed on the 360.  But there's a lot to learn from it.

If you 'dip' the carbs it will dry out the felt seals on throttle shafts. As long as you get all the water out and re-oil them it usually isn't a problem. Treks guide is probably the best one anyone can use for 360 carb DIY.  it covers stuff that isn't in any manual. The only caveat, if you want to run 'pods' carbs need further work to fix the 3K~4K missfire

I read Treks guide through and through haha.
You rebuilt them actually, PJ. What other work would it need?

The slide was stuck, so I took the right carb top off and set the slide back down and all functioned properly again.
I started the bike back up, and it is idling still around 3-4krpm.
I tried to adjust the idle but turning the screw doesn't effect anything. Also, adjusting he pilot screws dont seem to do anything either.

Are you saying PJ built your carbs?

Turning the A/F adjusters at 3-4k rpm?  You really won't see any effect. 

Sounds like you may have a vacuum leak or your throttle cable is maladjusted.

Cna't find any vaccum leaks.

Turned the choke on just to see what happens.

Obviously, it slows the idle down a lot. Open it back up, back to high idle. the right carb is sorta blowing some misted fuel out as well

The right carb is blowing fuel mist out of where?

If PJ has had your carbs in his hands then they need nothing other than a quick once over (after bouncing around the UPS truck) and gauge sync/tuning.

You can double check the float heights and operation.  PJ still sets them at 21mm as far as I know.  Keep them at his 21mm.

They mist fuel out of the right carb intake side. I am going to check right side intake valve clearance. Actually, might as well check all valves

How long ago did I do them? (or better, when did I send them back end of last year or 2019?) Were they the ones with slides gummed in?  If so, I washed them out pretty good but don't remember if they went through ultrasonic cleaner? So far, in about 10? years doing 350/360 carbs if there is a 'carb' problem' 99.99% of the time it's either charging, ignition or cam timing/valve adjustment.  ;D
