Without. I have only had one saw with a bulb (MS192T). Stone cold in the middle of winter a saw should "pop" with no more than 5. I do have an MS31
0 that has eaten a couple hundred cords. It has gotten some stubborn occas ionally and takes lots of pulls. I don't use it often any more (have bette r ones) so I haven't done anything about it. Annoying part is it will "pop " after 10-12 pulls and then next time I pick it up weeks later will do it with 2 or 3.Harry K
