Accelerator Pump Nozzle Stuck

I was hoping someone could help in identifying a part number on my CG 125 carb. (circled)

The accelerator pump valve/screw is stuck/blocked.
When I tried to get a Guesstimate the honda dealer place recommended replacing the carb, which I could just do myself, so doesn't really help.

I assume this screw is actually removable?

I think "Accelerator Pump Nozzle" might be the name for it? but I cant see it on the parts diagram.

It is likely to be a pressed-in part. I don't see any slots to get a screwdriver in and undo it, although you may be able to push it out from above.

Why do you want to remove it? A squirt of carb cleaner using the nozzle straw should clear it out. If that fails, try poking it through with a strand of nylon from a tough paintbrush. Do not poke it through with copper wire.

That parts diagram is a bit hard to read, I would imagine that it is pressed in like Robby says. You I'm not sure if it has a ball bearing in it or not, you could probably leave it submerged in some Acetone overnight and it would probably eat the gunk around it ball bearing if it has such.

Do you not know of anyone who has an ultra sonic cleaner? A few users on here bought them a while back IIRC.

Nah I don't know any other bikers really, and nobody with an ultrasonic cleaner.

If the bristle doesn't dislodge the blockage, I guess then replacement is the way to go, if original CG carbs weren't in such shit condition on ebay.

Would a copy carb do the same job?

it looks near identical

Send this guy a message, offer him like £10 or so see what he says, it's on sale, must be in his parts bin for a while now and he's sick of seeing it.

There shouldn't be any kind of one-way trickery with it, it should just be a jet. Any one-way trickery (and fuel metering) is taken care of by the pump diaphragm in the bottom of the float bowl. All that little thing does is turn the fuel being forced up into a finer spray.

As such, you don't need to be hugely anal about scratching it - it doesn't meter fuel as a jet does, so the tolerances aren't so critical. Avoiding poking things through with copper wire is just good practice for any brass part in a carb.

If you can find a replacement you may be able to drill that bit out, but I would be working on getting it cleaned up. If carb cleaner on a nozzle had no effect, the next step is compressed air.
