. . .was looking for one the other day! Found out that a piece of paper folded 4 times is an alternative in a pinch too

Folded paper measured with calipers to .010" is what I use. Business cards vary in thickness according to the paper stock and are usually more than .010". I'm going to check flexible plastic that comes in various packaging and find some that is the right thickness and use that.

Personally I like using the correct tool, the magnet on the flywheel and the steel gauge compliment each other nicely. If you’re going to get sheet stock to make one, you should consider steel.

Besides the above^^^

Wooden piston fork/support

Circlip tool

Bench vise/copper jaw covers. Saw mount for vise, that bolts to bar studs

Clean nylon rope for piston stop.

Assortment of flat and round files, for chains and to dress bars, raker gauge

Tool to clean bar grooves ( can make one from 16p nail)

Seal puller

Soldering iron.

Dremel and assorted bits.

Used truck/tractor tube to make ex/int block offs.

Large honing stone to dress gasket surfaces smooth and flat
 
Some weird ideas I've had for tools/shop stuff lately:

Bench vises of a couple different sizes with rubber inserts for gripping parts without marring.

One of those Workmate clamps tables with dowels surrounded in rollbar padding or pipe insulation for keeping saws steady without removing handles etc (making ones for saws and ones for carving, myself)

A hybrid sandblast cabinet/parts washer for cleaning saws. Compressed air with a solvent blast you can turn on and off with a valve.

A large assortment of small metric and standard o-rings, quad rings and other seals.

Assortment of tygon fuel lines

Magnetic parts trays, project boxes.

Torch tip cleaners for carb passages

X2 on lighting and clean area. Tape or caulk seams where screws or small parts could fall in the workbench. A roll of bucher paper you can use for a new work surface is nice if you are especially OCD.
 
Heat gun for heating up bearing pockets and an IR thermometer to see when you’ve reached the desired temp.

@Mattyo case assembly tool is worth it’s weight in gold if you plan on getting into lower end work. I have one and highly recommend it.
 
Wanted to add here the Walbro "W" tool and the Zama "Z" tool for setting metering lever heights in carbs.

A leather punch, X-acto knife, and a roll of fiber rubber gasket material and you'll be able to make your own gaskets.

A decent size zip tie cut at a 45º angle works well to clean bar grooves.

A adjustable air gap spark tester. This lets you test how strong an ignition coil is. A coil may be able to spark a plug in open air held against the block, but not have enough power to spark the plug under compression.

Tube of Permatex 518 anerobic sealant. Cures in the absence of air. Works very good for sealing metal on metal surfaces, like clamshell engines or cylinder/base surfaces on the larger engines. This same stuff is used to seal crankcase halves of 2 stroke outboards, all the way up to the large V-6 engines.

Having a roll or at least a couple feet of each common size of tygon fuel line is handy too.
 
A small Mag lite so you can see what is going on when your looking for air leaks. Buy a good one . I recently got one of those L.E.D. Leo lights and like it better than a Mag lite. It has two different lights in it , a kind of large light considering the size of the light and a small beam for looking into small areas plus it has a magnetic base which is great for working on vehicles.

I love my LED headlamps. Have several, favorite is rechargeable.
 
This really isn't a must have tool but it is nice to have around . A long screwdriver with plastic handle or a cheap mechanic's stethoscope to listen to what is going on inside an engine. I recently bought a cheap mechanic's stethoscope because I didn't have one and it is much easier and nicer for sound than using a screwdriver to listen for a bad bearing .

If you work on enough saws you can hear some are quieter than others on the bottom or top end. A screwdriver or one of those stethoscopes will pretty much pinpoint where the noise is coming from. Most saws are noisy in the area around the clutch but a marginal rod bearing has a different sound and is kind of neat to listen to what is going on inside an engine.

I thought one of those stethoscopes would work to hear air leaking out of a seal for a pressure /vac test without jerking the saw down anymore than you have to . Nope it didn't work for that. Oh well didn't hurt to try.
