Sorry for any inconvenience. I thought I knew where is the problem. You said it will die when you WOT? And somewhere leaking when you WOT? Try to use a CABLE TIES to tie the Dust Protection of the carburetor. Please see the attachment.
I just tried a .28 and recorded the needle setting.That is running setting not break-in setting.
High speed needle -- about 2 ~ 1 1/2 turns out
Low speed needle -- about 4 turns out
I'm using 0.4mm shims with 25% nitro,#5 plug.
Try it first. If you still have problem after testing,don't worry. Just send this engine to me. I will check it carefully. And let you know the result. But you know it will take some time.
