782 spark plug
 

I have a 1983 782 w/a series 2 motor. The question is I have seen the plug for the motor is a rv 15 yc4 and the same plug in a 17 style. I understand the smaller the number the hotter the plug. The question is which is better? the champ. or is there a better plug in another brand that u guys have used. I intend on using this for mowing and possibly other chores(possible tilling and maybe a 3 point?????) I have a 1712 w/a Mag 18 and used e3's in it. Any ideas would be helpful.:bigthink:

This may help........ Plugs

I run an autolite copper plug in my John Deere 317 with KT 17 series II. I don't remember the number I will look and post. I like the autolite copper plug better myself, however I'm not sure brand name etc makes any difference.

I also run Autolites in my 784.

I use the RV17-YC Champion in my M18

I run autolites in all of my cubs and send any cub I put my hands on gets an autolite.:beerchug:

Autolites are in my cubs, as well.

Autolites!!!!! :biggrin2:

Thanks guys, I think I will try a set of Autolites.:Thanks:
