Thank you all for the responses.
Having just spent a TON of money and hearing from you all, I believe the best course of action is to let the shop that did the work take care or it. If I start messing with things then I open a can of worms, I believe. If it was not a fuel problem, I would just fly it down to the shop and drop it off. Now, it will just take time to have them get someone up here.
I have no problem opening the cowling except as above. I USED to have a mechanic that would come to my hangar and oversee/sign off work we did on past planes: EZE, M20E, turbo Vike, and others. I need to look harder for a replacement. Last mechanic's wife got real sick so he dropped out. I am at 7CO0 near EIK and BJC. If anyone has any recommendations on a traveling mechanic in the Denver area, I am game.
It has to be a big problem. Otherwise, how does fuel sit in the bottom of the cowling for over 24 hours and not all evaporate? Fuel leaks and turbos mix very well. It's just the big boom that bothers me.
The good news is---no oil leaks!!
Take care.......... everyone have a great New Year!

Oh- and to respond to your questions: No fuel smell while flying it 3 days ago, but there was an unusual miss on take off. After I hit the primer a few times and super tightened the mixture, it smoothed out. I circled the airport for a few laps and went on with the flight. She missed again doing pattern work the same day. Both times on climb out. I landed at BJC and called the shop. The chief mechanic at AA said it could be dirt in a line or ..........etc,etc. I got her home without any issues or misses. I am sure he will take care of it. Just going to take more time to get them up here.
