Default Engine Woes

Ok...over the past w/end...I tried to start the break in process on my LD3/STS D5. I believe my carb may be messed up.It seems to be "gritty" if I try to open/close it and sometimes it doesn't even close with the servo movement. I know I shoulda stopped dead in my tracks and maybe posted then and see if I could get some help/info...but Im impatient
Anyhoo....I fiddled a bit with it and the linkage and got it to what seemed a happy medium. Once I got it started, it seemed ok for a minute or two. Now after that, the idle gets very erratic. Mostly it '
gets extremely high and doesn't want to come down unless I fiddle with the Th/Trim on the radio. A friend helped some, and again we thought it was ok.I started the engine and for a lil bit longer, the idle stayed fine.Then again, it slowly got higher and higher...really screaming. I decided to try a new plug and still the same problems. I am using Wild Cat 15 % which I believe has 18% Castor, and Rex 7-go5tf plugs.Also, I have only the copper .3 shim on the head. Any help/info is greatly appreciated.
On the positive side of things....the engine starts right up almost instantly.
