Default Neddles settings on West 50 engine?

Guys, I am on my second MagnumR with West 50 engine. First one got FUBAR[]

Using 10% fuel my main neddle is around 1 turn, the low neddle is around 2 3/4 turns.
The engine is idleling perfect, transition to hi is perfect.................My problem is that when I close the throttle barrel to shut off the engine, is does not want to turn off[&o]

The O ring under the carburator is compresed very tight between the carburator and the engine.
all the head and back cover screws are tight, so I dont know what else to do.

I have 3 other Webras 50GT Speed and I have adjust the low neddle and those engines are performing OK.

My first West 50 engine was adjusted the same way and perfome AWESOME.

One thing that I think is strange is that all my webras 50 low needle was 2 turns set from factory and I just close 1/4 to adjust the transition from low to hi. Do the west 50 low neddles is 3 turns from factory????

Another thing that I found is that the low neddle screw on this second west 50 is very soft to move. I check it and the vibration does not move the set up but could it be possible that the engine is getting air thru that low neddle screw????? I was thinking to take it out and put some teflon tape around the low neddle screw.......... What you think???

This engine is almost NEW. Less than a gallon[X(]

If you haven't seen it already, have a look at this thread


The engine not cutting is normal. I can't help as I've left the low needle at the factory setting and haven't had a chance to play with it much.
