Yeah I found out in the end its the motor, after the gun seeing 4 different owners and now seeing me, it is now pretty dead, can barely move the gears
And when I put my backup cheapy chinese motor the gun came back to life after the right motor height adjustment.
I thought it was the shimming this whole time but it was the TM motor that was dying
So now I am left with the option to get either a new stock TM motor or are there better choices?
I am guessing the Systema would be the best choice?
