Does anyone knows what plugs are good for these engines that were made by GRP?
What heat range should I use? I'm at sea level, air temps around 86degF and high humidity..

I'm thinking of using OS no.6, or should I use something else or colder/hotter?
Will be running the MR28 in a truggy..
Thanks in advance!

I ran these engines for a long time, i would suggest an OS P3, they last forever in those motors.
