Okay, big news..I think. I believe I figured out where my vacuum leak is, might be a far fetched theory but this is what I could come up with.

Since the needle jets are missing, air can get in thru the fuel chambers. That would also mean that the fuel levels are also low in the fuel chambers, so the floats are also set in the wrong position. Since the fuel is low, air gets sucked in thru the fuel chamber vent hose. When I blocked off the vent hose this morning, I could somewhat control the revs.

Is this a viable thought process or am I just going crazy at this point?
