Hi, I've just got myself a rohm twinmaster and wish to know how to ture the power up.
I've checked mine and it's shooting at 2.6 !
I've checked on line and found an old thread from a bloke who got his shooting at a little over 5.0 !
He had to increase the hammer spring as well as turning the power up. As an engineer fitting a larger spring is easy but I just need pointing is the right direction as to how to ture the power up.
Also any advise on to what I should go up to !
