New everything. The WSM overhaul kit. Bored .020", pistons, bearings, water pump, carbs, the whole 9 yards. Carb kits were OE, not some kit from wonton, I finally got it finished. Fired for the first time today. 20 mins at 900 rpm. Looking to double check WOT timing advance. After 10 hr easy break in on double oil. VRO is long gone. The info tag is long gone from the silencer. I have an authentic OMC full service repair manual. In Synch and Link it says to get the timing #'s from the silencer cover. Ain't happening, long gone. I've heard and read anywhere from 22 to 28 degrees. Your help here is appreciated. Kevin
