Chainsaw Repair

Dropped in on a mate Monday and he had his saw in bits on the bench dead coil priced local and was quoted 180 bucks to me thats  BS so I have some dead macs up in the rafters and am hoping one has a coil that will fit but my problem is this coil has so many numbers on it I dont know what may be compatible. Its a walbro coil made in mexico and has 3 rows of numbers
row 1     545-115801
row2      ma-82 283
row 3     16 m1 10183490      any one have a listing of what this may be and what may fit dont want to hassle him for more details dropped in on him tonight to find out his dad died last night so just like to find a coil and drop it off to him he has enough on his plate.


underneath between the magnets is white 82   an embossed 10     and an embossed type  xa

Thanks Kevin thats the one will see what I can find down under now that I have the poulan  to go in front of the part number I could find nothing researching under mac.
