I have a stihl 026. Starts on 5th or 6th pull. Bosch plug. 36 to one mix. I can understand it might take awhile if it has set for awhile. Im talking couple hours later or thenext day. Saw runs strong. Would like to yank on the rope a little less. Good fuel 91 octane,stihl oil at 36 to one. How do you guys do it?
