I set the mixture the old fashioned way for a SU. Procedure is in my Handbook. However; I will drive the steep hill behind my home and listen for the "PING". Advance dizzy until I hear the "PING" then back off a bit until I don't hear the "PING". This should work until "Father's Day" when I will be in Victoria, BC. Jim Walters will tune the +4 at that time. It was Jim that tuned My +4 just prior to my Key West and Europe trip.
