I have a new Saito .72 that has been broken in and seems to run well until... I idle down and then it quits. I have tried adjusting the low end needle starting at the factory setting of open 5 turns but don't seem to be able to make it idle worth a darn. I also put a new OS 4 Stroke plug in it, changed fuel (Omega Cool Power 4 Stroke fuel) but nothing seems to help.

Any ideas? I appreciate any help anyone can offer.

Thanks,
