I have cleaned and fiddled with it and it is running better. It bogs slightly at yield signs and under heavy pedal. The secondary or smaller barrel cover has no spring back, it stays where it is put but moves free and smooth by hand force. I don't know enough about it at this time to say more other than Thank You to everybody and any links you could send my way that might educate me more would be appreciated. I am waiting on a manual for it but the manual is in German and Ich haben fergessen mine deutsch!
