Is the engine using transmission oil?

Turn out the air screw and see if it idles any better.

If the idle speed picks up when your turn out the air screw turn the choke knob clockwise to slow down the idle speed.

Have you checked the condition of the reeds?

I haven't pulled the reeds out yet and i don't know if it is using trans oil. It did great in the leak down test which makes me beleive it isnt. The air screw had little affect on the idle, same with the idle screw although it did change more than it did when there were two o rings in it.

If it starts to run correctly after you shut the fuel off and that is repeatable,you are dumping extra fuel from some were.just because the float is set correctly doesn't mean that it sealing up completely I always check this by hooking the gas line up with bowl off and lightly lifting float to see if it shuts off completely debri can keep it from sealing or just worn out.once you get it to stop dumping extra fuel make sure to correct jetting

Pulled the float bowl off and manually pushed the float up with the fuel petcock on, no fuel cam out with even the slightest pressure applied so i know that isn't the issue. Put the new B8EG plug in gaped at .020 and same thing, no change in idle or throttle response. I pulled the reeds off to make sure they were in good shape and they looked perfect so cross that off the list. The intake port and reeds were soaked in fuel though. I've ruled out transmission fluid, the level has not changed at all and the fluid still looks clean as can be. I'm running out of ideas on what to check without completely replacing the carb.

Dreamer check to see if the motor has filled up with fuel. If so with help you can dump it out by pulling the pipe and tipping the bike on its head. If it is full of fuel be ready with an extra spark plug if it fouls clearing it out.

I have a 38 pwk that I would let go of. Pulling it off my bike to put a 39 back on. Works perfect. I just like the 39 on mine better.

Finally got it running today with the 38 mm pwk from the_steve_man. Running a 165 main and a 55 pilot. Bottom end is pretty rich and top could go maybe 2 or 3 jet sizes down but that can all be worked out with some time. Thanks for the help guys.
