Have any of you had problems with the tach sticking? It seems to rev fine but the tach needle will stick and it will jump around like its pulsing or not getting proper signal, I was going to just slap another cluster in, but I was wondering if any of you had seen this and what you did? It will not jump crazy but if it is isle it will stick at like 1200 whichI know is not correct then I rev it up it will bounce jerky toits highest rpm pont the engine saw then it will "jerk" back down. I don't think the engine is having problems but maybe something in the cluster.

Thanks
