Works perfect
Installed with no problem, started with first pull as advertised, arrived when they said it was coming in.

Restore your Honda 1 pull starts & fix running issues.
If you have a Honda engine (in this case, a 4-5 year old mower with Honda engine model GCV160) and are stumped trying to figure out how your once reliable, 1 pull to start up engine now requires many more, hot or cold, or won’t keep running once started (to include rough running / surging) this part is commonly the culprit. This part has everything to do with the “auto-choke” design of the engine, but can affect running performance, too. They wear out/ fail pretty frequently. Before you take apart your carb or replace spark plugs, etc. , remove your air filter element and check to see if the carb air intake valve is fully closed (as it should be with engine cold as shown in my pic), or if it is stuck partially open. Inside this part is a wax compound that expands/contracts with engine heat, and controls a small pin-like rod in its center. The pin contacts part of the carb intake air valve control arm. Engine cold = pin retracted and permits air intake valve to fully close (aka full choke). Engine hot = pin extended and prevents choke from being on, which isn’t generally needed to restart a warm engine. These pins usually fail to retract and just plain get stuck in one position, creating havoc for all things choke, idle, and running related. In my pics, you can clearly see how the pin of the old one is just stuck extended out a bit. This mower made its way into my shop because it suddenly required 7-10 pulls to start and surged once running, when a few weeks earlier all was fine with it. Shop manual references using a thermal paste on the body of the new part when installing. I never have and never had issues. Pics I included should help those unfamiliar with the parts location on engine. Getting the old one out frequently requires use of a needle nose vise grip pliers and a fair amount of wiggling. The aforementioned mower also surged badly until fully warmed up, and occasionally thereafter. Upon replacement of this part, engine is back to 1 pull to start and no surging issues.

These work fine.
To remove the old one, grab it with good pliers. I put a small amount of high temp silicone sealant on it before sliding it in place.

so far so good
Just installed Thermo Wax Assembly and below components on a Honda Motor GCV160 with auto choke on a Troy Bilt mover and below recommended choke control, choke actuator (Thermo Wax Assembly) like many others here. Of course note gaskets placement and orientation as may block some ports otherwise. Worked perfectly and stopped surging. All these parts are inexpensive so happy there. I'd bought same carb just 2 yrs prios and stopped surging but it returned ! So this time replaced all 3 interrelated components.

Fit Honda GCV160
If your mower will start first pull then idle crazy, and or die and will not start. First clean the carb and if that doesn’t fix it, then it’s likely this quick choke feature that’s prone to failing on these mowers. Use some needle nose to pull out the old one.

Important part
I’m not even sure what this thing does, but it brought my mower back from the dead. Good stuff.

not ALL HRX217's use this one! Mine uses a round one,
It's important to know that not all Honda HRX217's use this one; it did not fit in the hole for mine. My HRX217 (2010 model) uses a round one that looks like brass in color. Make sure you know which one you need before ordering one.
