I agree. My SP-81 spools up much faster and revs higher than my PM700, despite having many many more hours on it than the smaller saw.
So you found some NOS engine parts eh? Good deal. Can't wait to see that saw up and running.
I just picked up a 'junker' SP-81 for a 'junker' price. Dirty and a bit corroded (no pitting though), with a locked up engine and soft AV mounts. It's complete however, and will get torn down completely, repainted, and reassembled with NOS parts. Randy had been trying to get
my NOS P/C for his project (and I don't blame him), but I'd been saving them 'just in case' I found a 'rebuilder' saw. A buddy found this SP-81 in a local shop boneyard and grabbed it for me. I really like running the 82cc 10-series saws, and am glad I'll have a 'pretty' one as well as a seasoned, former logging saw (my runner came from a local logging family). The 'pretty' rebuilt saw will still get ran however. It's not going to be a shelf queen.
My 'new' saw has a 33" McCulloch branded Windsor sprocket tip bar. My current runner SP-81 has a 3
2" unbranded Windsor sprocket tip. It's funny that those two lengths were both made for these saws. The 32" bar carries better on these saws IMHO. I'd seen the 33" bar listed in a few IPL's before (#91284, and uses 106DL of 3/8), but this is the first one I've seen in person. Haven't seen the 32" bar listed in the 10-series IPL's, yet I've handled a few. I'll shoot a couple pics of the dirty bugger and put them up. Funny thing is that I thought my runner looked dog-eared...................well now it looks 'new' in comparison to the second saw.
Yep. The big 10-series saws are the only 82cc Macs. Homelite made 82cc XL700/800/900 series saws as well as several 82cc EZ/EZ-6/7-19/600D/etc large frame saws. The large frame McCullochs jumped from 80cc to 87cc, skiping the 5ci/82cc number.....
PM8200 as well. Same basic saw as the DE-80. I've never seen one in persion. Haven't even seen a pic of a PM8200. I have seen the IPL however...
As Randy said, the spitback guard/collector was sometimes bolted to these carbs. Also, the basic HL body casting was used in several configurations. On some saws, the air filter assembly bolted to the back end of the carb. Those holes serve no use on a saw that doesn't have a spitback collector or an attached air filter, but it'd make no sense to have a second set of dies to cast a carb body without them. The mixture needles were also sometimes placed at the back of the carb instead of the side (often on saws that had the attached air filter assembly). An HL will have blank, unmachined hole sections (with 'H' and 'L' cast over/next to them) for whichever needle location wasn't used on that particular carb (be it on the side or at the back).
