hi everyone
i still couldn't get this regapping thing.. i know why it is done and how but i couldnt get the distance measure.. most people regap it at 0.30 but 0.30 what mm inches etc ? and from where to where is this distance on the spark plug .. looking at the picture below is it between a and b or a and c or other?

ps: please dont tell me to get a haynes or other manual we dont have them in my country
thanks for helps

 

it is the gap between a and b, and you get a little gapper from the parts store for like $1.00 and gap them, easiest thing you could EVER do....

 

i dont think we have those gappers here in my country... what is the measure units?

 

.030" wich is 30 thousands of an inch.

 

thanks guys

 

do you have a valve last measure dealie? i use those

 

.030 feeler gauge works good

 

yeah i thought those would be helpful too.. thanks
