Jump up and down on the thing!
Bead breaking? Can just beat the snot out of it with a small sledge hammer. OK, maybe not. I like the link...using pieces of 2x4 and some goon muscle. (I have enough of both). Just make sure you use a clean piece for the lever or you'll end up with just a pile of kindling and splinters in your forehead.
To clean plugs I've found nothing better than a piece of safety wire to dig out the little globs of lead that can form. Since I added the Lightspeed ignition a few years ago the lead fouling dropped off to almost nothing. For general cleanup, I wire brush them with a small soldering brush, blow 'em out with compressed air and check the gap. Good to go. I bought an abrasive spark plug cleaner but then thought that even a tiny bit of sand or walnut husk or..whatvever those things use, is not what I want to introduce into the engine. Dirt is bad. I think this was addressed in the SkyRanch engineering manual as something to be aware of with the abrasive cleaning methods. By the way, John Schwaner's book is THE BIBLE of air cooled piston engines. Highly recommended.
For regular tools and consumables to maintain an RV, I like to keep on hand:
1. bag of copper spark plug washers. (Use them once then toss 'em.)
2. safety wire, both sizes
3. shop rags
4. silicone spray lube
5. baby powder for tires/tubes and the baby if you have one of those.
6. oil filters
7. oil of whatever flavor you like.
8. gaskets/locking washers suited to the type of fuel metering system you
have.
9. beer.
10. more beer, if your annual inspection comes due in the summertime.
11. still more beer if you find a blown jug or metal in your oil.
12. lemon pledge, or Plexus for the canopy
13. fuel lube
14. differential compression tester
15. mag timer
16. box wrenches
17. torque wrench
18. electric and manual screwdriver. (I hired Manuel to operate my screw gun but he keeps quitting. Says I don't pay him enough. Hmmph.)
19. Set of tires, mains and nose or tail.
20. Set of tubes as needed.
21. Wheel bearing grease.
22. Plenty of screws, washers and locknuts. They're cheap.
I'm sure there is more "stuff" needed to keep an RV happy and healthy, but this is all I can think of right now. After five, and currently in the middle of, the sixth annual, these items are necessities for my carbureted RV8. I needed item 11 THREE YEARS IN A ROW. I replaced three cracked jugs in as many years, then did the fourth just as a pre-emtive strike.
Have fun.
