Well.... After mucking about with the needle, float, hoses... She starts and runs! and no leaks.....

But only for 30 secs or so before dying...

So fuel / Air is coming in, and the spark's fine.... not sure what's going on now...? If I slow it down on the throttle, say half way, it takes another 10 or 15 secs longer before dying again...
Some joy...but still frustrating... help.....
