Resistor and Non-Resistor spark plug

I work on those old tractors for a living. With solid core metal wires, some tractors I gotta kill the ignition before the garage door clicker will work. Have also had aftermarket electronic ignition kits fried from solid core wires. Gotta use resistance plug wires with those kits.
The only plugs I've really had problems with over the years have been Bosch, plus they're the most expensive of the lot. I stick with NGK aswell

Instead of the threaded top plug that will vibrate loose and cause saw problems, and leave aluminum dust in the plug boot, get a solid top.
NGK BPMR7A nut - #4626.
NGK BPMR7A solid top - #6703.
Genuine Made in Japan NGK #6703 are only $1.32/ea at RockAuto. Way cheaper than from the dealer. So affordable there is no need to worry about resistor and non-resistor.

In my 80’s Husqvarna dirtbikes with the SEM ignitions using resistor spark plugs and resistor caps will kill the SEM ignition. With chain saws and SEM ignitions I’m not sure.
Has anyone tried the Chinese spark plugs from huztl/farmtec yet? Only $0.59 on sale. I don’t use that many spark plugs.

Absolutely not. I would not even use free ones unless I was in a pinch. At $1.32 for a genuine NGK there is no question about it.To save 73 cents a plug i would not even consider chinese plugs. Last order i made from huztl they put five plugs for free on my order........

I wonder where the NGK plugs are manufactured in Japan maybe? For now but we know most of the manufacturing does switch to China sooner or later.
In the 80’s I sent machine tools I built to China one lathe had a 124”/chuck and weighed 200k. It took five trailer trucks to carry it. The Chinese took it off the boat and uncrated it on the dock. They had no way to move it , some of the pieces were 25k tons. It sat in the rain. Yet there bare foot doctors who ride bicycles from village to village can cure throat cancer go figure.
At that time the us goverment only allowed 2 axis CNC controllers out of our country. I guess so no one had the manufacturing capabilities that we do Incase of a war.

The NGK BPMR7A (4626 and 6703) are made in Japan, or at least the ones I have seen are.
NGK also has spark plug manufacturing in the US (Irvine) and Europe. I'm not sure which product categories are made there. None are made in China.

Maybe, but using china made plugs are equally tempting as is visiting these gentlemen.....

My ex urologist just took off to another state. I won’t go into detail but he screwed up with me. Now a really awesome young urologist surgeon is trying to extent my life a tad longer. I’m not the suing kind.

That is far too young for all of them. Sorry to hear you lost them at such a young age.

Hindsight is always 20/20 though. I wouldn't judge yourself too hard while looking back.

Is that an alternate for the NGK BPMR7A?
Why do you like the Denso? Maybe I should try some.

Yes. Well, price helps but Denso makes premium stuffs. Get yourself a box. The regular W22MPs without resistor are quite a bit shorter, if your modded saw requires it. I have boxes of both in my shop.
