Cutting out at WOT

[ReeV0]

Hi all,

I've got a brand new Jato 3.3 that has recently been broken in. All runs fine, idles fine, but cuts out at WOT. I can't seem to figure out what the issue is; online says it's too lean but there's plenty of blue smoke and temps are under 120c/250f... Any suggestions welcome.

Have you tried to richen the hi speed needle? If that doesn't work, lean it out. Just because it has plenty of smoke doesn't rule out being too lean.

Yep I initially started out very rich, Break-in conditions. It was spitting out unburnt fuel

Any way you could provide us a running video? Hearing the engine could help us nail it

Is it fully warmed up / pre heated to operating temp? Any bubbles in the lines?
It was broken-in for the idle cycles and slow driving? These would be the first WOT attempts?

I’d start with richening the hsn
