What is the best setting for a 83 n/a for the plug gap? I think my book says 39-42. i have set them i think at 41 before, but i didnt know if one setting was better than another. thanks for any advice.

PLUG GAP TIP

Some people recommend when using a high performance ignition/coil to open the plug gap to .050 (or wider). This is said to create a larger, longer duration spark to increase power. But on high compression motors conventional wisdom is to keep it at .045, because as compression goes up, it's harder for the spark kernel to start. Crane says to use .045 for "offroad and high-performance usage", MSD says .050. NOTE: if you open it up to .050 on a stock ignition/coil you will only weaken the spark. I played around on mine and I like .045 with my MSD 6A, feels a bit "snappier" than .050.



found that if it helps... and i would have said search like nismo but your a fellow GA Z driver

basicly saying the farther you go past .041-.042 on a stock ignition the weaker the spark you will get, but on the other hand the closer you get the weaker/smaller the flame
