this has probably came up more than once in this forum i assume but i rebuilt a liner and im having problems keeping the follow through at 0%, i made sure there is a flat hit on the spring w/ contact screw, the spring and tip of contact is clean, but im going back anf forth from 10-13%, now i dont know how much this will actually effect the performance, but id rather have it at 0, i also notice when i back the contact screw off the flt goes down to almost 0, but then i have the problem of running a large gap and its not something i want for my liner, i like the dime gap rule of thumb gap, so what else can i do? would too much or too little rubber band tension effect this? or the bend of the needle (too much to less)..i know number arent everthing but id like to have 0% stl
