Craftsman Trimmer Carb Adjustment needed

I have a Craftsman trimmer model # 358.798530 that needs a carb adjustment. The carb has two adjustment screws...idle and a mixture. The owners manual says to start by turning the idle speed screw out by 4.5 turns and turn the mixture screw out until it stops. But I am missing the limiter cap on the mixture screw so I don't know how far to turn it. Can someone tell me a good starting point for the mixture screw?

Thanks
Steve

I don't know which series carburetor you have and the break-down doesn't help either...so, start out at 2 turns out and adjust from there. Allow the engine to warm up to operating temperature (3-4 minutes) and listen for a good 2-cycle sound at top RPM.

I check the carb and it has WA-227 stamped on the bottom. I guess this is the model. It is a Walbro. It also has N27 stamped in another place.
