Hello,
What is your idle gap set to for this specific engine? That's really what I am looking for, continue reading for a small back story and explanation.
I've read conflicting information on the idle gap for the S-25. I've read that the manual was wrong and has been corrected, but not what it was corrected to. I've read to ignore the factory spec and set the idle gap to 1 mm as a starting point. I've read from the manual that the idle gap should be approximately 2 mm and not allowed to close to less than that.
After years of trying to tune my Savage with a gap of 2 mm with no luck, I found that the smaller the idle gap, the better it runs. But this also affects the LSN settings and so on. I am dialing it in, finally after it sitting on the shelf for so long, but am curious as to what a solid base line is to start from, especially for those having a hard time tuning?
There's a lot of information out there about nitro engine tuning but how specific do we need to be with our brand of engine? The factory settings for the S-25 seem to have led me down a frustrating path in the past. There's a list of the popular manufacturers here and their factory settings, but for the S-25, I gotta say and believe it's wrong for the idle gap. There are fine adjustments to be made, sure, but half of what the MFR recommends? Seems a bit too much.
It's fun getting back into nitro, and I am now teaching my 15 year old son how to take care of his buggy, and hopefully tune it properly.
