OK. Almost got it working. It idles nice, moves up nice, and run nice at full throttle. I tightened down the carb base and the carb and also found that the throttle was turning the wrong way which is why (I think) it wouldn't idle.

One more issue. I can't seem to get it to shut off using the transmitter's low ilde button. It looks like the throttle leaf is all the way closed and it is still running. I know there is a taper on the leaf and it may be mounted the wrong way. Is there anyway to tell by looking at it through the air intake?

Below is the exploded view from the Walbro website and it looks like my leaf is the same way as in the picture. The dimple slit is up towards the top carb housing.

Thanks.
