Don't spray any solvent in any of the lines!! And I don't recommend soaking the carb at this point.
Okay, okay lol. Wait what? Don't soak it? What I'm supposed to do with it then!?

Spray it down as best you can. The C3M carb has a sealed welsh plug that is susceptible to some solvents other than fuel. If the plug looses seal you pretty much now need a new carb. The paint should come off with some light cleaning anyway.Okay, okay lol. Wait what? Don't soak it? What I'm supposed to do with it then!?
Removed from the saw yes, cleaning the lines out with break parts cleaner is fine. Shooting cleaner down the impulse line with it still connected to the saw is a really bad idea.Once fuel lines are disconnected, I've never had any problem using carb cleaner to spray out the carb. Then I just reassemble and and fire them up according to directions. Each saw I have calls for a little bit different startup procedure. Happy sawing!

Spraying solvent in the cylinder or cranking case will displace the oil and wash the oil off the cylinder walls and internals. You don't want that.
Do you have a 6421? Seem to know an awful lot about this thing. Just found this:

So WD-40 for the cylinder? I want to ensure nothing abrasive fell into the cylinder. What can I spray into the fuel/oil lines or is that unnecessary?
I own several 7900's and have owned several more. The 7900 is the same saw with a bigger top end.
WD40 is fine, but unless you have a real reason to do so I wouldn't. You're over thinking this. Put her back together and start cutting.
So you bought a "rental" saw from Home Depot?
Do all Home Depots sell their rental saws?
hmmmmmm
I may have to check, I have a Home Depot 60 miles South of me.
That residue looks like something that was in solution and was deposited when things dried out. Give the air filter a good cleaning. If you take the carb apart lay it out in the order AND orientation which you removed it. A sonocator works great to clean out the body, use a proper solvent, and rinse well/dry when done.
Most HD's have a rental dept. They have quite a bit of stuff for rent. From hand-held power tools to towable scissors lifts and cherry pickers.
And yes, they do rent chainsaws.
The one in Delaware was also selling a used splitter. Regular price was over $1,600 and it was selling for about $900. That may be my next purchase. Now back to putting this saw together.
