Working on a 029 super for a buddy. After doing some carb setting research it sounded pretty standard for Stihl saws. Seat the H and L setting and back out 1 full turn should get you close then optimize from there and set LA by plug color. His saw after warmed up doesn't want to idle, bogs and dies intermittently. Have to feather gas, sometimes can catch up to it other times cant. Tried adjusting carb last night and the H and L don't even have a full turn of adjustment. Completely seated to full out is only about 3/4 turn. Did a little fiddling with it and was able to get it to idle up by making small adjust on L and LA but need to go out and cut a little to see if issue goes away. Is there a standard setting to start with regarding this saw ?
