After all the help from you guys, today I had not only great engine runs but got to know the Barnstormer.
I even got it going so good, I was able to play with diffrent props, best overall for my needs is an APC 9x5.
I think there were a bunch of minor things I fixed from your suggestions, but I'd bet it was the wrong "O" ring for sealing the venturi causing most of my problems.
Thanks men for all the help, Jerry
