No I haven’t had the spark blow out even with the high compression engines, the grooves stabilize combustion.
First off thank you for taking the time to help me. Very cool and much appreciated.
I couldnt quite get the line right in paint, but the line does go between the valves just to the exhuast side of the spark plug hole. I finished them up the best I could by hand and some 'precision' files.
I will post a pic here in abit. The total length is just under 1/2" and the deepness is about .050". I am unfortunatly without precision instruments so mustly going by 'eyeballing' the situation.
Grooves look good despite being kinda small. I think the close up pics are making me think they should be much bigger ?
