my new therapist 78 cb400t

[farmer92]

So i last year i got a little bored and decided that i needed something to distract me in my free time and after a little searching and 400 bucks, voila a little cb400 of my very own. Almost as if on queue my free time suddenly disappeared and now here we are, almost a year later with nothing done. Now that my free time has come back to visit, i can start working on this.

this is how it sits right now in my basement, chillin in the corner.

Been waiting around for parts to show up from the world wide garage sale and so i decided to get my paint on with the side covers and the gas tank. First i did the side covers,

And then i did the tank.
At first i was just going to fill the holes in the tank with bondo and prime and paint it, but that bare metal was just to damn appealing and in the end i ended up with this.

Just need to clear coat the tank, polish and stick the honda badges back on, I'm still on the fence about them, i may paint them the blue to match but we shall see.

God damn Quebec and it's stupid, worthless st-jean-de-baptist day... nothing worse than seeing that your parts were tracked to with 10 miles of your house, but having every god damn business be closed because someone decided quebec needed an extra drinking holiday.

Finally received some cylinders in the mail. They may work they may not, but for 35 bucks i'm a gamblin' man.
Got the engine cracked open and once again i marvel at honda's engineers ability to design functional EASY TO WORK ON vehicles.
Screw you, New Holland, Bombardier and Polaris.
Any how, removed the heads and cylinders, and misc stuff.

So, the bike runs... sort of.
I got sick of waiting for my new gaskets to show up so i threw it together with the old head gasket even so there is still 140 psi compression on a cold, unbroken in engine so i think it will be okay. There is a light oil leak from the head gasket but the new ones are on the way and it's about 3 hours work to change them so it will probably be fine, but there is a slight snag. It appears to be running extremely rich. It will barely idle, and it can sustain about 6k rpm in neutral, any higher and the plugs foul. I removed the air filter element and it runs far better, there is a slight stumble when cracking the throttle hard but other than that it is okay.

tl;dr
running rich, are there air jets in the carb that could be plugged and causing this?
