Here is a large spark plug adapter for a larger FM Z engine.  I am pretty sure it is for a 10hp a 15hp FM Z, check the measurements against you engine to be sure. If you want to talk about it 419 789 1159

SPECIAL NOTE: This is for a FM Z engine but not all of them, if you are not sure its what you need please ask questions before you purchase it!  I'm not taking a return because you have no idea what you're buying!

  • Very Rare!!
  • The tapered part is about 1-3/4" to just under 2" in diameter and that tapered area is about 1-5/8" long
  • It is about 2-13/16" in total length
  • This is for the large hole igniters, it will not fit the engines that use the smaller setup
  • Should be for some 10hp or 15hp FM Z that originally took an igniter.
  • Looks like is has a 1/2" spark plug in it, I have not tried to remove that plug.  If its stuck I am sure it will loosen up with a little heat.

I am a well known collector and dealer of antique gas engines, parts for them, and related items.  I try to list all my items very accurately so the buyer knows exactly what they are buying. Out of respect I ask you to please actually read the descriptions and look at all the pictures before buying or asking questions.  I am glad to answer questions but I’m not always that good at emailing people back. If you can find a way to talk to me with your voice you will almost always get a quick response. If you message me please try not to sound like a caveman.  I have terrible grammar myself so I understand but sometimes it is very difficult to comprehend what some people write.


All of my items are listed “AS IS” and “NO RETURNS”.  If I make a mistake on my measurements or you feel something is not as described please let me know and I will try to make it right.  I think most all of my customers with a normal level of sanity are happy.

My shipping time is set for 5 business days, weekends and holidays don’t count.   I ship out most items quicker than that though. If you are worried about how soon I can ship an item please ask before you buy it.  I travel a lot and have a family so I am not always on call 24/7 when it comes shipping items. I think most people would agree that I do an extremely good job of packing items so I guess it's worth the wait.

Please keep in mind I also really like to buy collections of gas engines and parts.  I pay very well and am a very active buyer. I am looking for items for my collection and resale.   


Thank You!
