Have a craftsman 6.0 easy start. At wits END. new plug, gasket and O-ring on carb, filter, gas, and oil. Coil tests a 4.8. Prime 5-8 times it starts and runs for 5 seconds and dies. does this twice and 3rd time runs but seems to have a miss now and then. Desperate, need to sell this thing bad. Thanks, RLH:mur:
