|---|
| impervious to the effects of Ethanol and additives in modern fuels and does not |
|---|
| deteriorate with age. |

| 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. |
|---|
| 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. |
