RE: DLE 30 replacement carb
Is this something that should be done right away(Walbro kit), or does the carb performance just deteriorate slowly?
Does the carb need the k10 and d10?

These all have a 12.7mm venturi
WT-257 Nice carb, right size, high speed nozzle check valve, no accelerator pump, and no choke
WT-603 Right size, high speed nozzle check valve, primer bulb, and it does have a choke
WT-668 Primer bulb and choke as well as the high speed nozzle check valve
WT-644 Primer bulb and choke but no high speed nozzle check valve

RE: DLE 30 replacement carb
As stated before, the definitive carb is the Walbro 813. It is rumored all over the place as having an accelerator pump but I cannot see any evidence of it in the Walbro literature. The carb has no choke. it has a "32" in the venturi as the others mentioned here. It has the high speed nozzle check valve. But the one generally available everywhere has a primer bulb.
This carb, minus the primer bulb is the standard carb from the factory on the Syssa 30.
All these carbs mentioned so far, are 1/2" carbs and are either standard Zenoah G-26 carbs or sold as replacements for use on a Zenoah G-26.

RE: DLE 30 replacement carb
Thank you for these several responses - now that I know about Dave's Motors (thanks to the posts here) I searched for the WT-813 there - it's listed with the following text:
"Walbro WT-813 high-performance carburetor. This is the carburetor recommended by Zenoah for upgrading your RC-style engine. Engines with the standard carburetor (WT-603, WT-668, etc) tend to experience a lag in low-end acceleration when tuned for peak power. The new carburetor includes an internal acceleration pump to allow faster recovery as throttle increases. Carburetor specs: Walbro WT-813. 15.88mm bore, 12.7mm venturi, independent tunable high and low speed jets. This carburator does not have an internal choke.
Fits Zenoah G23LH / G2D / G230RC / G260RC / G231PUH / G260PUH / G260PU / G231PUM / G260PUM engines. Also fits Chung Yang CY23RC / CY26RC / CY27RC / CY29RC / GP290 engines."
So I wonder why Walbro doesn't mention the accelerator pump also.

The parts list for the 813 shows no piston, accelerator kit part number Illustration number 58

This ball is located at the right side of the carb body when looking at the butterfly from the cylinder side. This carb is not designed to be reassembled.

RE: DLE 30 replacement carb
This is a "32" carb with an accelerator pump WT-513
http://wem.walbro.com/walbro/product...&Series=WT
It looks like a pefect candidate as it also has a choke
This carb has a fast idle linkage on the throttle arm that some people may want to remove?

RE: DLE 30 replacement carb
Wow all this talk about replacement carbs for DLE engines. The carbs on my current production DLE30 and 55 engines work as well as any genuine Walbro carbs I have ever owned. If I was looking for a replacement carb for similar engines or as a DLE replacement, I'd go right back to the DLE carb again. Hard to beat, especially considering the cost.
