I gave Dean Stone some Merlin plugs to try out. I have found the 2010 and 2011 to run well in the Evo. The 2009 is the hottest of the long plugs in the 4 stroke / 2 stroke line. These plugs are the same length as the stock 46 NX plug and put the ignition point where it needs to be. They go up in heat and compression from 2011 to 2010 to 2009. You should not have to shim the head with the 2011 even on high temperature days.

I have also used these plugs in YS 4 stroke engines and they do well in those engines as well.

I have to admit I'm a Merlin dealer. I may have some of the Merlin plugs listed on Amazon soon.

The Merlin web site is at http://www.merlinglowplugs.com/main_page.html

Cool Beans,,, So just stay with the Merlin's that we use in the 426 motors ~ that's easy enough :)

Don,, Thank you

Scotty,

Merlin yes. The same as 426, probably not. The 2009, 2010, ans 2011 plugs are extra long like the stock Evo 46 NX plug.

I have tried the regular length plugs like the 2002, 2003, and GloBee 2016, and they do not do (as) well.

Start with the 2011, and if you aren't blowing plugs, try the 2010. You will probably blow the 2009 unless you add a head shim.

I'm meeting with the producer of my backplate mounts next week, and I'm taking Evo 46 NX shims to see about getting them in 0.001", 0.002", 0.004" and maybe other thicknesses.

I will probably be getting fuel clips as well.

I now have more of the Merlin Glow plugs on my Amazon store at StegallHobbies.store.

You can go to https://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Dtoys-and-games&field-keywords=stegallhobbies+ama424 for plugs appropriate for AMA 424.

I have two more plugs to list in the Globee line. The hot 2016-7 and the cold 2016-10, but I have them on hand for direct orders.

The 2010 and 2011 seem to work best in the Evolution .46NX engine when turning it up with the APX 9x6.

The 2009 can be used at lower rpm's with bigger props in Club 40 Gold.
