I was able to install this on my carburetor without even removing the carb or fuel line on my chainsaw and my brush cutter. Super easy to install and the machines started on the second pull. You will never need to repair a carb ever again and your tools will start every time. I learned about this on YouTube (Steve's Small Engine Saloon).

Fit my Husqvarna blower. Easy to install and worked as described! Would buy again.

Worked perfect on a 33cc craftsman chainsaw with a walbro wt324 carburetor. It’s a must, to go to walbro website! They have a video on installation and adjustment of the needle lever. Runs perfectly afterwards after a little tune, from trying to adjust before replacing.

Not my first rodeo with Walbro carburators and they can be a little fiddly. This upgraded part works wonders on my older trimmers and blowers. Easier starting, tuning and smother running. I'll be using these for any carburators like this. Would get five stars but I think that the price needs to come down. Just my 2 cent's

Replace your black rubber metering diaphragm with this.

It is difficult to be certain which carbs this kit fits. The Walbro HDA series, common on mid-sized chainsaws, are the wrong size for this diaphragm kit, and Walbro seems not to offer a correct one. Instead, purchase a CTS diaphragm pack. I did after cursing the spiral kit, and the new diaphragms seem to work well.

After replacing The original walbro twice with cheap Chinese knock off carbs over the past few years. Found out about this diaphragm. Put it on the original walbro and its fixed.
