Dear Tom,
It is most gracious of you to offer. A friend of mine now has the model and is in the process of resetting the valves. All of your posts been extremely helpful in trouble shooting this problem. I am quite sure at this point that something I must have done is basically wrong. Others who have installed the Pegasus carb have been very happy with it. A fresh set of eyes often sees things that were previously unseen. If my friend can't make it run, I will take you up on your offer. Shall I PM you if I decide to ship the engine?
