So, recently I had to change ldt hk416 nylon gears etc to metal,
Put her back together and instead of 275+fps I was getting 30 to 120 fps.
I have spent over 2 weeks trying to diagnose but I can’t figure it out.
So far I can see that aoe is good, and sector delay is good as seen on this pic, also teeth alignment.
The gears line up just the same as old nylon ones to the teeth and sector delay timin
Also checked nozzle head to t piece and it just seems to be off slightly.
Yet still have stock tappet, nozzle, cylinder head, stock piston head even.
Only changed piston to metal, and gears to CNC, and new tappet return spring to match. Seems to have good pressure.
Currently I’m at a loss as to finding the fault.
Any help appreciated.
