What is a good plug to use with the Evolution 46nt. The Horizon site suggest using a Hanger 9 Four Cycle Super Plug! Could this be to use a 4 cycle plug?

I they are out of stock on that plug right now. But the Saito SS, or OS F or Y-S plugs would work just as well.

I used a OS A-3 and Tower power plugs in the Evolutions. They are 2 stroke plugs. Seemed to run well.

w8ye, Thanks for the reply! I will try these.

Jim,


The OS A3 is a hot plug; the hottest OS have to offer and so is the previous, no longer available, Tower plug, which was an A3 clone.

The current Tower Power plug is a medium heat plug, similar to the OS #8, the Enya #4 and the Novarossi C-6S.


I don't know which of the two Tower plugs you were referring to, but if it was a late model unit, it is a significantly colder plug than the A3.
You could have leaned the mixture strength quite a bit with it, after changing from the A3.


Barry Williams says the Evo .46 runs better on hot plugs.
I'll take his word for it, even though a medium plug would seem more appropriate for this engine.

Maybe its lower C/R (to make it easier to handle as a beginners' engine) allows this.

I had the old Tower plug from 1999
