I did more reading in the service manual from walbro. I can have a metering problem ,since the metering hole to atmosfere is UP and on the side where proppelor pushes the air. I have an Idea how to fix that, Imay have to do a cleaning and blowing on the carby, After I got the gas in and I took the pump plate out , Ifound some fine aluminum on it.
Now ...How I can drop a 1000 RPM's on idle, from 3000 to 2000.

I drew my set-up, any diffrent ideas?
