Thank you for letting me know. It is good to know that i am not the only one with this problem.
I have spent most of the summer fixing this car, and wondering what i did wrong.
I have spent some money on a conversion set from New Era to fit the NX76 engine in my savage,
and about 4000,- Norwegian kr. on this two engines and they are both completely destroyed.
It`s a good thing that my wife does not know how much money it costs :-)
I will try to contact my dealer in Norway first, and if i cant get a new engine from them i will cal Cen USA.
thank you again....

If there is more people out there with the same problem i would like to here from them to!
