One essential tool for Lyco / Conti owners is a short 7/8" or 22mm spanner, for the spark plug tops.
A stubby one proved elusive to find (without buying a complete set) so I cut a normal one in half 
The full size spanner is not only heavy but can easily overtighten the aluminium nut at the top.
Or, even better, modify the ring spanner half as follows:
@Michael
Why do you overlook a type pump ? What would you do with an under inflated tyre ?
Do sparks fail often ?
I tend to agree with the spare main wheel.. even if I don’t have one ! ;-)
However, can you change a tyre yourself (if you can borrow jacks etc)? I wouldn’t know how to.
Replacing aircraft tyres is in most cases a non-event compared to automotive ones: undo the bolts and the hub comes apart, no need to exert any brute force.
I have merged some similar threads and here’s a list I posted in another thread a while ago:

Any maintenance shop should have this capability, but you need to trust them that they will actually do it. I know for a fact that sometimes this doesn’t get done.
Basically you cut through the paper element so it can be spread out on a newspaper. Any debris gets caught in the outside surface of it – so a lazy person can just inspect it by pulling apart the “gills” without doing any cutting of the paper element.
You also need to sort out a toolbox, with some essentials:
Other bits include the standard green dishwashing scourer pad for cleaning up the prop leading edge, spark plug thread lube, and of course Grease 7 which does nearly everything on a plane.
For lubing universal joints in control linkages (which cannot be dismantled) ZEP45 is one of the better products (not WD40 
).
For windows, use Plexus and a 99p Tesco facetowel which is totally absolutely guaranteed to not have been dropped on the ground. Similarly the aircraft cover must never contact the ground (with its underside surface and preferably not at all).
that’s what you need:

I love it.
WOW… 4000 quid… here you would get killed for that
Bahco are good tools though. I also like Facom.
I don’t believe that kit weighs just 6kg. More like 16kg.

And the best way to carry small quantities of grease is in a large disposable syringe, it makes the application very convenient. For injecting very small doses into hard-to-reach places you can even put the needle on, it still flows well enough (though my experience is with 22CF instead of 7).

same here, you have to wait for some discount they’re offering. Still not a bargain.
But with that, you’re set.
I’m not even sure 16kg is enough … might be heavier ;)

Good list – I am missing some things. What I’ve been doing lately is moving tools from my big red rolling toolbox to small canvas bags as I use them. Up to two small canvas bags now, and I toss them in the back when I go on a “trip”.
I use these, but you can get something similar or better on amazon.
