Ouch, it's sad..

I believe what grizz really said that if you followed posts from this thread, especially what grizz was writing it you needed to be at least in tuning ball park...otherwise what can I say, from thousands Go's you got black sheep
I would send a mail to the shop from where you bought and it might be sort out for you

I still trust on Go engines, look on this thread, there is soo many happy users
