I'm not a "real" Homelite guy, but I'm a pretty good fake.
It's 5.01 CID and was the first chainsaw of any kind with electronic ignition. I think it was an option, so yours might not have it. You can tell without pulling the flywheel if it says "Phelon" or "REPCO". Wico made the points system, R.E. Phelon Co. made the electronic system.
Great saw. Looks good, doesn't weigh too much, has loads of power from that hemi-head jug. Oh, check the cylinder nuts while you're in there. The old ones tended to loosen before they put locknuts on. I have the last of the line--a Super XL-925. Same basic saw, but with little improvments here and there that don't matter. Got mine for $10 at a yard sale in new condition.
It sure is a beast for the size. A 24" bar with 3/8" FC seems to make it happiest. Don't know about the 800, but the 925's are selling in the $100-150 range last time I checked.
Mike, what happened with that stud? I thought all the 800/900 series has flathead bolts that were pressed in from the fuel tank side. No way to pull one without breaking the saw in half.
The 700G is the gear drive version of the 700D. Or vice versa. Made in 1960, 5.64 CID. Mike's page has more info:

I know what you mean about neighbors. You should have seen the look on the face of mine (great guy, but buys from Sears like a good doobie) when I walked over to say hi carrying my 110cc Jonsereds 111S with a 24" bar!
