Default G 380PU no start

Greetings all from a Newbie to the forum.

Can't get the Zenoah G380PU on my Skywalker to start. This after sitting for a couple seasons due to other commitments. Before that, engine started easily.

Engine readily starts with a squirt of starter fluid but quits immediately.

Checked the forum for help to make sure I was starting correctly and to pickup any advice tips but no joy yet.

The key seems to be no fuel being delivered by the Webro carb. I have cleaned, disassemble/assembled the carb several times including compressed air and probes to make sure all channels are clean but I still cannot get the carb to "suck" fuel into the engine. Gaskets are in tact, vacuum diaphram looks OK and appears to be operating the intake plunger valve.

( WOT, thumb over venturi, low speed jet at 1.75 turns, high speed at 1.5 turns, rotate the prop several times but no wet finger)

So I am thinking whatever it is that is not allowing fuel to be sucked into the carb is my problem.

Thanks for any suggestions or pointers on what I may have missed.

Don
