Description: Genuine Walbro K2-WYTA Spiral Metering Diaphragm Upgrade Kit - Includes Brass "W"
Gauge
Editorial: Walbro's patented spiral metering diaphragm upgrade kit allows you to convert your
carburettor from the traditional rubber metering diaphragm to Walbro's ethanol
compliant spiral metering diaphragm. The new spiral metering diaphragm is
impervious to the effects of Ethanol and additives in modern fuels and does not
deteriorate with age.
Replaces OEM: Walbro K2-WYTA
Fits: This genuine Walbro K2-WYTA spiral metering diaphragm and gasket upgrade kit is
suitable for use with selected Walbro carburettor models including but not limited
to WTE-1, WTE-6, WTE-11, WTE-13, WTE-19, WTE-21, WTEA-2, WTEA-3, WTEA-4, WTEA-5,
WTEA-6, WTEA-7, WTEA-8, WTEA-9 and WTEA-10-1. Please refer to the notes below.
Features: A membrane with a high grade teflon film in the centre and a stainless steel
spiral diaphragm - impervious to the effects of Ethanol and other additives found
in modern fuels.
Currently over 500 Walbro diaphragm carburettor model numbers can be upgraded to
use the new spiral diaphragm kits.
All parts (except the metering lever) are contained in a clever installation sleeve
to make assembly quicker and easier (refer to notes below).
Standard Pack Quantity: 1
Please Note: Warning - These parts are extremely durable inside the carburettor but fragile to
handle - DO NOT bend or crease the membrane when handling or during assembly! The
stainless steel spiral is more forgiving but care is still required when handling
it. The metering lever must be replaced with the new one supplied, please reuse the
old metering lever pin. For a 5-pack version of this upgrade kit without the brass
"W" gauge use our part number K7-WYTA .
Note: Fitting instructions -
1. Remove metering cover, old diaphragm and gasket.
2. Remove the metering lever and replace with the new one supplied, reusing the old
metering lever pin.
3. Reset the metering lever height using the updated version of the brass "W" gauge
part number OMK500-528 which is included in this spiral diaphragm kit. The
adjustment point on the brass gauge is on the bottom, the indentation you need to
set the lever height is below the word "Spiral".
4. Install the new gaskets and diaphragm onto the carburettor while still contained
inside the installation sleeve (Important - install onto the two metal pins, making
sure that the word "TOP" printed on the installation sleeve is facing up).
5. Hold the installation sleeve with one hand and put the metering cover on over
the top to hold it down.
6. Install the four screws and start them by just one turn each.
7. Then remove the clip off the end and pull the installation sleeve out, then
torque the screws down normally.
Footnote: When comparing this fitment application information to your carburettor model
please disregard all letters (A, B, C) and -1 that may be at the end of your
carburetor model number.
