Cool. The thin wire type thermocoupler with the tiny “bead” at the are the hardest to use properly in my experience. They really need to be physically attached to whatever surface one is trying to read. I was trying to use it to measure the temperature on a new soldering iron’s tip, unsuccessfully till I learned from the experts on the Dave Jones electronics board “EEVBlog”. I was told to make a small solder bridge between the irons tip, and the wire probes lead, now they were physically connected, and measurements were accurate. The one I’m linking below, (for the benefit of all) is great to directly read the surface of our 30mm dishes, but obviously wouldn’t fit through a carb cap hole.
Now if you can squeeze a bead tip through a carb cap, you could at least measure the AIR TEMPERATURE, inside the cup, and perhaps see what if any differences you see in your test. You won’t be getting surface temps because even if the probe “bead” tip was touching it, without some solid pressure or being physically mated, the readings won’t be accurate or terribly useful. These bead type thermocouple wires, work very well when submerged in ice cold and boiling water, two tests used for double checking many temperature probes as well as the DMM, since we know what those two temperatures are supposed to be. I’ve also been able to squeeze the “bead” in between the end wrap of the heating coils, when not installed and ran some open air tests. There are uses for these “bead” type wire sensors, just not too many that I have found, thankfully the usually include one in every DMM I’ve bought, as they are cheap, and not too durable, though I have abused a few.
Below is the KType handheld probe (can read over 1,000f), I believe Baron23 originally recommended in another thread. At $14, I wasn’t hoping for much, but after comparing to my other probes, I felt it was quite accurate and I still use it now and then to make sure my #1 probe the Thermapen Pro (575f MAX TEMP!), is accurate to a few degrees. Showing on Amazon, as “no longer sold”, but like most Chinese clones, probably the same factory making them, and rebranding. So you will be able to get the same thing with some shopping. You’ll also see these exact same probes on websites selling for $40-50, ripoff!
Now if folks own a fairly standard DDM (digital multi meter), with standard banana style female lead sockets, you will need the adapter below, as I did, none of my DDM’s have the smaller “blade type” KTYPE socket, though some meters do, never seen one myself.

Feel free if you ever want to discuss your measurement tools or techniques, just something I’ve been enjoying, along with the vape results.....
I've banned myself from using Amazon too, irresponsible cocklords that they are
