SELLING Walbro RWJ4 carb (OE for 372XP X-torq)

[Derf]

I have two Walbro RWJ4 carbs. I was going to use one on my ported 372XPW but I'm really digging the work Poleman did to my Zama C3M, so I'm keeping that one and letting these two go.

$50 shipped (each) Paypal f&f

Pics coming soon

Carb 1 (left side) has a shorter idle screw and a plastic piece on the throttle lever to hook a bullet at the end of a wire. It is marked RWJ4

Carb 2 (right side) has a longer throttle screw and is missing the plastic piece. It is marked RWJ4B

Complimentary ultrasonic cleaning if the buyer wishes. Otherwise sold as is.

Does the Zama you’re using have the same throttle plate opening?

The throttle plate is quite a bit smaller on the Zama, actually even smaller than the HD12B that came on the OE 372. I think the RWJ4 is aost 19mm, the 12B is like 17mm, and the zama is like 16mm.

The Jets on larger carbs are matched to the larger Venturi, so a larger carb = more air and fuel. But Poleman modified the Jets on the Zama so it flows more fuel. It works well for me.

bump,

these make great carbs for a 372xp OE as well for an upgrade
I believe you can also run them on a 390xp and 395xp.

$50 for the pair? Sorry for the low ball but don’t hurt to ask

I'd be interested in carb #1 with the plastic thing for the cable end, if it's still available.
