Tm Mp5k HC full auto misfire issue

[Ersanu]

Gents I’ve upgraded the internals of a tm Mp5k hc and installed a Titan mosfet.

 

Gear ratio 16:1 and since I’ve installed a 31k warhead ronin motor with 11.1v lipo I’m getting constant misfire on full auto.

 

I’ve tried 7.1v lipo and still same issue. I’ve tried AB at 20 and off (battery protection off too). Don’t know what to do. Also the tapet plate pushes the piston forward well before the main spring is released. Really confused with what it could be.

 

Tried with pre cocking off and on. Still problem persists

 

Shimming and AOE is perfect

 

Tappet plate moves freely without rubbing anywhere.

 

Tappet spring is nice and strong

 

No delay chip installed

 

Nozzle lubed and moves freely

Tried different battery brands just to test and still same issue

 

fyi I have an M100 spring installed. Getting between 341-349 fps on semi.

 

thanks
