What a difference a plug makes. Yanked the Torch and put in an NGK into the 4375, and changed out the oil for Fram hm syn. Runs smoother with less vibration. Or is it just the placebo effect?
Put the NGK in the Predator..

So it is a good cheap Chinese generator once you swap the junk Chinese spark plug for a Japanese one?
I've found that NGK plugs really do make a difference on the HF generators, had several that had a pretty rough idle with the Torch plugs that cleaned up perfectly with NGK plugs.
So far, yes.
I don't have a ton of hours yet. But for a small generator , the 4375 is really good on fuel and is 240v.
One of the smallest 240 units I found. Just under 16 hours run time on a 4 gallon tank.
I ran mine 50 hours solid on the last power outage.
Will it last 2000 hours? Don't know, may never know for standby use.
Uhhh, better?
Obviously Torch plugs have really bad quality control issues, some say they are fine and some not. My first experience with a Torch plug was with my first Super Recycler with the Toro TXP engine. About half way thru the summer it stopped starting on the first pull, pulled the plug and it was almost covered in soot to where the gap was almost closed. Showed dealer and he gave me a NGK, problem solved. My next new Toro with the same engine came with a Bosch 
Same here, while my snowblower ran "ok" it was lacking and took many pulls to start from new. Replaced the Touch with a regular NGK and it seems to have more umph in the tough snow and it now starts on the first pull without fail. I recently put in an NGK iridium plug in my Briggs & Stratton generator that had the factory Champion plug. It ran ok but was a bear to start, usually took 5-7 pulls to start. It's a large engine so it's not easy to pull start. Just by changing to the NGK iridium plug it now starts on the 1st or 2nd pull and it "seems" to run smoother.
Unless you had a misfire, I suspect the placebo effect.
I reluctantly say I've had a very similar experience.
It was a Chonda HF Predator 212. After 5hr break in as a kart engine built up with modded jets, it was..."off".
I swapped fuel. I swapped oil. Sluggish still and got worse.
Swapped plug for a Champion platinum that was used out of the Deere LA-175 V-Twin?
Perfection.
Sent it after sustained WOT launch to 50+ MPH.
110% adrenaline. Zero fooskin' defects. Y'all should have seen that kid's face when his pop accepted my delivery commission on Christmas morning.
Priceless!
In chameleon, chroma blue and clear coat and competition orange hi-temp coated engine block and chrome accents.
Nothing to fear in a Predatoror other Chinese cheap junk. But electrics and ignition you simply can't compromise.

I've swapped many old tired engines for Predator 212cc's on old equipment for customers, and now I include NGK plugs as part of the swap. They don't run noticeably smoother, but start MUCH easier. The Predator engines start pretty easy, but I was initially getting come backs a few months later with the Torch plugs because the engine would go from taking 1-2 pulls to about 8 pulls, especially on snow blowers.
I want *to preference that I personally would not use but have tried the Torch spark plug, I would not install them in any customers engines either.
But.....here's the thing, I tested several new and with some miles on them looking at their wave patterns on an *oscilloscope. They did not show anything unusual. I also completely took a couple apart to see how well they were manufactured. Found nothing of concern.
These test do not confirm any longevity performance of a spark plug and I should point out that even top brand name spark plugs seldom will be as efficient as new with over 15k miles on them.
again to be clear I personally will not use them.
*over the decades whenever a new spark plug came on the market I always tested them in an engine and looked at what there performance was on an *oscilloscope

The same thing with my Troy-Bilt snow blower with the Power More engine with the Torch plug. It started taking more pulls to start it and it seemed to have more difficulties in heavier snow conditions. I changed to a NGK plug and it now starts on the first tug and chews through deep heavy snow much better now. Though the Torch plug color was a light grey/tan indicating a good mixture/burn, I guess you can't go by that all the time.
Id say its placebo. Spark plugs are not going to make a noticable difference. I remember when those Crossfire and Splitfire spark plugs were all the rage. They were never anything but a marketing ploy.
^^
^^I use many time in many response an oscilloscope and the information you get from it disprove many DIY, info, butt dyno and many other theories.
My Ariens Deluxe 24 came with a Torch plug. It became increasingly difficult to start and reached the point where I had to remove and clean the plug in order to start it. I replaced the Torch with an Iridium NGK plug several seasons ago. It starts easily now. I had two other pieces of OPE with Torch plugs. They weren't giving me problems but I swapped the out with NGK Iridium just for peace of mind.
The next time you visit a Lowe's that sells snow blowers have a look at the Ariens branded replacement parts vs. the other spark plugs. The Ariens brand Torch F7RTC is $5.99 whereas the Honda brand NGK BPR6ES is a dollar less.
