'bigmac' - Yep, my original thinking was the same as yours, but I believe I've done all I could in that regard, including the items you mentioned. Before I rebuilt the carb, I drained the gas tank, cleaned it out, put a new fuel pump on and additional in-line gas filter, changed the filter in the glass bowl filter, pulled the cables, serviced them and reset them, and added fresh gas. I did all the less-expensive maintenance things I could do. I believe you are right on with your comments about finding the cause. I hope to be in a position to "do it right" in the Fall with a engine rebuild. The comments I've gotten from all the Stovebolters should get me through the Summer. Thanks to all.
