For some month ago I bought a set of 61mm terminators for my 3L type4
http://cal-look.no/lounge/index.php/topic,3960.0.htmlBut like others I have problems with the 3,5mm glass ball one is working and the other is crap

then I tested the spare set for my old 51,3mm also crap

But my 13years old Berg steel ball 3mm from the 51,3mm is stil working fine

but is 3mm fine for lets say 300hp with a fuel preasure on 0,25 bar / 3,5psi ??
Or do I have to buy a lot of 3,5mm to get one working set ??
