So this one has me stumped. Low use 2511 with a muffler mod, carb delimit and BG delete. Saw runs very rich. Only tune it will run on is L 3-3/4 out, H all the way in. No pressure or Vac leaks. I’ve been through the carb. Popoff seems okay, lever height is correct, diaphragms look good, needle good, carb looks near new inside and out. I replaced carb with brand new, exact same tune. It starts and runs on this tune but still cokes up spark plugs within 1/2 tank of fuel.
Timing numbers are: Ex 112, Trans 132, Intake 68.
Could a bad coil cause this? The saw runs well with the goofy tune until the spark plug cokes up. My tach says 12,100.
What am I not thinking of?
