So, I cross threaded the nut on one of the engine studs and one it was tight, it stripped out the threads in the engine block.
What's the recommended repair here?
Helicoil or Keensert?
New M6/M7 Stud - is 115mm too long for a standard Puch Maxi? If so, do you just stack a few washers?
New M7 Stud - will it fit in the cylinder and head without having to re-drill them?
