Well everyone, I think I've got it but I'm almost embarrassed to tell.
Thursday morning I installed my new Delkevic exhaust then fitted the intake rubbers back on. I hit the start button and it cranked and cranked but nothing. I gave the airbox a few squirts of starting fluid and it slowly fired up and then revved to the moon. I shut it down immediately and then tried starting it again and it fired up and again revved to the moon. Since it was revving way up, I pulled the throttle cable from the holder on the carb but left the barrel end in place. BOOM, it fired right up. I put the cable sleeve back in the holder and fired it up and it idled but was still slightly high. I backed the idle screw way out and it still didn't drop to where I thought it should be. I tightened the adjuster at the throttle grip all the way so it was bottomed out, and it was still slightly high. Last thing, I grabbed an adjustable wrench and very slightly bent the throttle holder down until the idle stopped dropping (maybe 1-2mm down). And now, as soon as I hit the start button it fires up and runs like a dream. Revs up well and sounds great!
I knew the carb rubbers not being on would not help it run but with them on a few weeks ago it still didn't want to fire up. I knew there was something simple going on and I'm so happy its running well.
Thanks again to everyone for the help and suggestions. This is the first motorcycle I've owned and worked on and I've loved it all.
