Brand new Saito FG 21, first tank (4oz.) first run (not on video) was for 15 min of 34 thousand rpm with needle valve at 3 turns open with a MA 15/6 prop.
Let her cool overnite, then today...
This was the second tank with gas mixed 20 1 with Stihl's hp ultra 2 cycle synthetic oil. Hand starts nice after 2 chokes, even cold! Still at 3 turns main needle, then closing to 2.5 turns at mid point. Very rich, lots of burbling, but nice idle and transision!
