Easy to follow and thorough step by step tutorials do it yourself (DIY) to help you with your broken lawn and garden equipment including snowblowers.
I do my best to teach you how to easily diagnose problems the fastest, quickest and most efficient way with real repairs beyond just replacing a spark plug. These tips are for both the homeowner and shop owner.
Whether it be a handheld, two stroke, two cycle engine like chainsaws, weed eaters, string trimmers, grass trimmers, line trimmers, hedge trimmers, strimmers, brush cutters, leaf blowers, or four stroke, four cycle units like lawn mowers, lawn tractors, snowblowers, pressure washers, generators, ride on mowers that need parts installed or replaced, I’m your go-to guy.
My favorite brands of spark plugs are NGK and Champion and are the ones I recommend.
I’ve been a small engine mechanic for many decades and also run my own repair shop so my videos are loaded with tips and tricks that I have learned and want to share with you. You will also find many tool and product reviews from top brands on my channel as well.

Fix 99% of non starting issues by replacing this simple part!
Keep up the good work ! Had that problem
I have a gcv 200 but it has nuts that hold the air filer box on. So when I take them off only the box comes off. The black plastic piece that the thermowax sits behind doesn't come off. Any suggestions?
If i have replaced that and it stays open whats the next step?
Is there a thermo wax cartridge on a hRR216VXA ?
Thanks very much.
This fixed my problem perfectly, but it only worked for one time. The next week, the same problem and the new cartridge has the pin sticking out again. Any ideas on why it would do that so easily after one run?
If this part has failed would it cause a no to hard hot start issue? I've wracked my brain, eliminated carb, fuel, plug and coil.
I’ve looked at numerous videos without success. This gentleman got to the point. He enunciated his words so he could be understood and he showed a step-by-step clear process so you could see how the parts were assembled. Thank you, thank you, thank you!
I just paid a mechanic to fix this exact problem on my Honda. Frequently I learn by trial and error, mostly error. Now I know how to fix the issue for a lot less money.
Thank you, sir! I appreciate this so very much. Exactly the symptoms with my own Honda mower. *You may pronounce the letter "Z" however you choose to*, by the way.
I also appreciate the part number listed in the description using lower-case letters to make sure to clearly indicate letters vs. numbers.
Dony do you prefer the briggs auto choke set up or the Honda? Seems to me that the Honda is simpler but what do you think? Great video thank you.
Thanks. My Honda wasn't starting. I figured it had something to do with the choke and your video helped me get the right part and fix it. I'm good to go now.
I still don't know why they didn't make a better system that carburetor that's just way too many gaskets why didn't they use a stud system that had a nut on the end of it seemed to slide it over the end. Thanks for the information. I didn't know that part was even on a Honda
In your video you can clearly see that the fuel cut off switch was turned to the off no fuel position. Causing your lawn mower not to start. You will later see in the video that when it starts he turned the switch to ON position allowing fuel into the mower.
Thank you so much for this great video. This solved my problem and my HRX 217 starts on the first pull again. Thank you.
I am having the opposit problem. The pin sticks out and the mower will start, but after it warms up the engine slows to an idle.
I have the same set up on my Husqvarna mower. Same Honda motor. Choke works properly. My problem is once it comes off the mower starts to lean surge. Where am I looking for blockage? I took the screw out of top of carb and sprayed in there but no change. Took bowl off too and sprayed,nothing.
Great video as well as others you do! Mine is GCV160A0 with electric start and has been having the difficult to start problem since it was new at April 2019. It wasn't very bad at first but has gotten progressively worse such that it has to completely cool down to get it to start. I am meticulous about running 89 to 91 octane non-ethanol gas and keeping it very clean and I run out the gas in the carb at the end of the season before storing it for the winter. I have a four year warranty. I was under the assumption that this is a warranty issue. I even took it to an authorized Honda repair shop where I paid a $30 diagnostic fee believing Honda would reimburse for it as well as the other repair costs and parts. Unfortunately Honda will not warranty this part even though mine still has about two years of remaining warranty. The repair shop diagnosed that it is the thermowax part, but Honda claims it is a normal operating characteristic of the auto choke. Auto choke to me means the choke automatically adjust no matter what the temperature is. If I turn it off after getting to operating temperature and leave it for a several minutes it won't start. It tries to start and sometimes I have tricked it by moving the governor, but usually not successful. I am really bummed that Honda will not warranty this. Anyway, through my research it looks like the thermowax part number of 16620-Z8D-305 has been superseded to part number 16620-Z8D-842. Do you know if this is the case, and if so, is it because this new part number is an improved part such that it is more reliable? Thanks!
Excellent! This was my exact problem and the solution worked – spot on!
Thank you for the diagnostic video and instructional on replacing this small part – the Thermowax Choke Actuator.
I want say thank you i fixed my honda .
