Default Long 1/2 Inch Spark Plug Type Identify

Hey

I need a long 1/2 inch spark plug with the same thread as a Champion X.
On YouTube I saw a video with a long one, but I can't identify it. Does someone know the type?
The link of the Video is shown below
https://youtu.be/vkECxLcLR98

Thanks a lot

The plug in the video appears to be a Champion 32, if so it is an extremely hard spark plug to find. A few years ago I was lucky enough to get a set for my BIG FOUR tractor and it now starts and runs so much better with them.
I believe it is used mostly in engines of the headless design with low compression and a large space between piston top and plug mounting hence the long reach.

Thanks for the reaction.
I need one of these for my engine, that is a copied beeman. First it has a Champion A25 but it didn't run wel and I made a longer spark plug and it fired right up, it is only not made for hundred hours .
Is there a remake from such type spark plug?
Or where can I buy it?

I would need to see the head design to have any idea. I was using Model T plugs in my BIG FOUR and yes they worked but quickly became fouled with carbon resulting in erratic running, loss of power and hard starting. The main problem being that the T model plugs did not reach far enough down into the compressed air /fuel mixture resulting in only partial firing and consequencial plug fouling. Have you a picture of the Head showing the internal position of the plug ?

Here is a picture from the head.
The spark plug is 0.5 inch to short.
It is a Champion X.

I have some of the very long reach 1/2" pipe thread plugs for sale, Champion 32 type and some Splitdorf made plugs of the same type. Advise if interested, Lanny Baron, 516-426-1098

Exclamation Re: Long 1/2 Inch Spark Plug Type Identify

Look on Ebay for Chamion #34 Gas Engine Special or Maytag pipe based spark plug (for uprights, models 82 and 92 hit and miss engines). Same plug, but one has the a Maytag name on it. These plugs are hotter than the 32 and less expensive. They won't foul as quickly as the X, if at all
