Walbro's K1-WYTA patented spiral metering diaphragm upgrade kit in a 5-pack withoutthe brass "W" gauge. These repair kits allow you to convert your carburettor fromthe traditional rubber metering diaphragm to Walbro's ethanol compliant spiralmetering diaphragm. The new spiral metering diaphragm is impervious to the effectsof Ethanol and additives in modern fuels and does not deteriorate with age.

1 (1 pack of 5 kits)
Warning - These parts are extremely durable inside the carburettor but fragile tohandle - DO NOT bend or crease the membrane when handling or during assembly! Thestainless steel spiral is more forgiving but care is still required when handlingit. The metering lever must be replaced with the new one supplied, please reuse theold metering lever pin. If your workshop does not already have one, Walbrorecommends purchasing the brass "W" gauge (part number OMK500-528) to properly setmetering lever height. For a singular version of this upgrade kit which includesthe brass "W" gauge use our part number K1-WYTA .

Reset the metering lever height using the updated version of the brass "W" gaugepart number OMK500-528 (sold separately). The adjustment point on the brass gaugeis on the bottom, the indentation you need to set the lever height is below theword "Spiral".4. Install the new gaskets and diaphragm onto the carburettor while still containedinside the installation sleeve (Important - install onto the two metal pins, makingsure 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 overthe top to hold it down.6. Install the four screws and start them by just one turn each.7.

Fantastic, I always review on the promptness of product arriving and your company passed with flying colours. The product has also passed with quality too, good job and keep up with the good service and you will do well.

Previous one lasted 2 years, though would have been much longer if a bolt coming off the mowing deck had not caused it to deteriorate quickly without my knowing it. Overall, I've been very happy with the quality of these belts. Have used them now for 7 years. Mowermerch store was quick and reliable in postage time and package arrived in perfect condition. Highly recommend.
Excellent product and second to none service
Took a bit of fitting to my Ferris s65z but I wish I knew about this item before.
Best of both worlds, can mulch and side shoot
No problems
Would recommend this amazing product to anyone
Ty very much Mowermerch
The blade steel needs to be of a more tough material.
Only used once and the blades have not withstood the test.
Just as well that I bought 2 sets, as I don’t think they will last as long as the previous blades.
