Never had any problems starting Conti TSIO-360 rich whether hot or cold, unless of course you flood it priming with the pump. I did find sometimes the 200hp ones didn't want to stay started without the fuel pump on occasionally when very cold.
The more important issue is when you stuff up the priming and it doesn't start, then it needs divine intervention to get it going;
better to go back inside and have a cup of coffee and start all over again in 20 minutes.
sounds about right.
I can't recall if I've used the non-turbo ones.
The funny one was the PA31, I have been told about 50 different starting methods, the one that worked the best almost every start was the one in the book.
