when i was having the pins blow out of my 11cc it was because i had way to high of compression. of course i didnt realize that until i went through about $60 worth of plugs, expensive lesson. so my guess would be if your blowing them all the time try shimming the head up a little ;) ;)
ok so i heard about the flex shaft crimper for making the square ends so does anyone know of where i can get one or who makes them? i have a ton of flexshaft material and want to make my own
in washington you can run pretty much year around as long as it isnt pouring down rain. this year i think we swaped weather with california because we have had nothing but sunshine for the past few months.
