I’ve used both the PWK and PWM and I’ve noticed that the PWM is very sensitive to a fat pilot jet down low and I’ve experienced this too on occasion. Then it disappears after like 3-5K and rips. Does it get better or worse as the day gets hotter/colder?

I’ve also had electrical problems give this symptom too. Check your connections and solder them so they have no change to wiggle.
