Got a 99 cr125 with a pump around fuel pump, and a PWM carb. I haven’t driven it in about 3 months. Took her out today, and noticed, right after being push started, I have to slowly roll into the throttle or else it bogs down. This only happens at low RPMs hot and cold temps.
I was messing with the knob on the carb, but forgot where it was set. Which way should I turn the knob?
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.

I noticed I was having this issue this past weekend as well. I agree it may have something to do with the pilot circuit being rich, although it does sound like a lean bog. I’ve pretty much ruled out the main jet and needle since they’re common sizes and slightly on the rich side. The choke knob should only adjust idle, so I wouldn’t suspect that.
