Thanks i put the castor in the fuel...... it helped some but i was still unable to get it to run right.

I noticed that there was a significant amount of fuel/oil residue on the bottom of the crankcase. I unmounted the engine an started the tightening all the screws process. I found that the two bottom screws on the back plate were loose. I tightened them a good 3 turns before they were again tight. I think air might have been leaking in through the back plate, which is why i think i found it so difficult to tune. I also drilled the air bleed hole one size larger.

Between these three things, the fuel, backplate, and bigger air bleed hole,...... I was able to tune out the engine in 20 minutes!!! When i was drilling the air bleed hole, i noticed some residue in the original hole..... I dont know which of these things fixed it, but it now idles at 3000 rpms, passes the tilt up test on both idle and full throttle!!!!
It is FINALLY in tune.

Thanks to everyone for all of the advice!!!! :-)
