I too must have the CAD, seeing I own 6 running chainsaws.
I bought a Homelite XL12 about 15 yrs ago used, was a great saw. I had it tuned several times. It finally got to running real rough. Took it and another Super XL12 I had bought on a deal and told the guy to get parts there if needed. He called me and told me the Super was a better saw in good condition, needed coil from old saw. We went with that. I have a bow on that saw.
I have a small Homelite XL that I bought new in the 80's, been a good lil saw. It got hard to start, wouldn't idle. I left it on the shelf, bought a new Poulan as my limbing saw. Biggest POS I ever owned. And I did loan it one time, has never been the same.
I bought a new Homelight small saw in December, the toolless adjusting system. That too is a piece of crap, chain will not stay tightened. It made me appreciate my older saws. So I then started buying old homelites for parts at an auction. Bought a lil Super XL for 15.00. Ended up needing fuel lines on it and a new primer bulb, great running lil saw. 25.00 total investment.
I then got my old Homelite XL out and rebuilt the carb. It too is back to being a great lil saw. I had a repair shop sell me a new bow to go on it for 20.00 and only charged me 18.00 for a new chain to fit it, longer on the bow saw. So now I have a lil bow saw, a big bow saw and 3 limb saws.
So I was back at the auction and bought a Homelite XL12 "BlueBoy". It is painted Blue and made prior to 1970 I later learned. I bought it for parts if ever needed. Paid 5.00 for it. Complete saw but no chain. Looks rough but all there and looked clean in the tank and carb. I got it home and checked it out, had good spark. I shot ether in it and low and behold it started right up. I then put gas in it and it runs great, nothing to do to it but put on a chain which I already had from the other parts saw I bought years ago, had a almost new chain and bar. It needs new paint, but a running XL12 for 5.00.
Still looking for parts saws. Bought 2 and both turned out to be good saws, one only needing gas & chain, the other fuel lines and primer.
I like my older Homelites. They seem to work well for me, easy to work on, parts still available. But I still can't get over the running XL12 for 5.00.
I said earlier I had 6 running chainsaws. I forgot about my Ryobi pole saw and my lil electric pruning saw, that makes 8 running saws. Homeowner use only.
