Don't have the laptop here or I'd give you the cal / tun numbers I used, but I took them directly from the chart for my OS (and actually I was just putting up the #3 version of the OS I was already using as a #1).
It did take awhile to get her started but I get the same thing anytime I zero the trims, so I did what I also do -- used the idle controls the first time to get her warmed up. After that, it was all good and no more hard starts.
