Hello Larry,
That is about what I use. I must admit that I can't really get used to the way the Wasp runs, fueled and propped that way. I have been flying small stunters from the 60s and they were designed mainly for a good 1.5 cc diesel. I just can't get used to such a small prop and high revs! I keep getting the feeling that the nose of these stunters are blanking out some of the airflow from such a small prop!
Proof of the pudding says that I am wrong and the models fly better than I can. Just shows how ingrained habits can be wrong!

Regards,

Andrew.
