Bought a Homelite WIZ last year at auction and it turned out to be a dud due to me not being able to check compression due to no pull cord. Ended up having an ant colony living in the crankcase and had destroyed the internals. So again this year I was able to find yet another old saw at auction but I can not find any info on it. The tag is labeled Wards Chain Saw and the model number is WR550. I can not find any info on this saw model in particular. Is it just a re-branded saw made by another manufacturer? Looks like there is some old yellow paint under the newer paint. Looking for any info I can find on it (ie: cc's, year, etc). Thanks!
