funktree, expect the idle to drop quickly or run rough if the WD40 starts to fill in the leaking areas. It sounds like a lean condition and I suspect you should use a #48 pilot jet/#100 pilot air to get the idle consistent. Taffy, we did get sidetracked by the main jet/main air jet discussions. I remember your first few attempts were very favorable without the APJ. I'm still interested in hearing what you find out as variations are tried. I still have a book of notes on my jetting tests.
