Fixing a Walbro WG8 carburettor on a Polini 80cc Paramotor

At the Bore Chaser fly-in on Sunday 21st April I met a pilot who was having engine issues related to carburettor problems for over a year.
The carburettor was rebuilt at the fly-in, but even though the jets were cleaned out with carb cleaner and a new carb kit installed correctly, with correct meter lever height and pop off pressure, it still didn't run properly. There was only one thing to do, rebuild it again and this time put it through an ultrasonic bath.
I have produced this video to document the process of rebuilding a Walbro WG8 carb and I have included all the information I have researched over the past few years by providing links to the southwestairsports website and some links to youtube videos to help other pilots rebuild their carbs, specifically the Walbro WG8.

My first time rebuilding a carb I did not use that gap tool and it caused me all sorts of grief. Keep making these tutorials and keep us content creators in the sky!

Great content Andy. I'm currently rebuilding my carb the wb32. The last flight at the bore mine run like dog shit causing me to burn 4 litres in 20 mins on my evo 100. I did not know the the metering lever can be out too. I will check that on mine. However I cant find any information from vittorazi regarding the pop off pressure for my engine. But hey ho. Again thanks for sharing. It's always helpful 👍🏻

Hi, it was mentioned, that the temperature should be at 175. Mine is running at full throttle (for several minutes) not more than 165. It means it is still to richt?! Motor is Polini Thor 190Evo. Consumption is about 7h/hour!

How many turns should the short needle screw in to the carburator? The needle with the cone

Hello again. I can see this carb is the new one for the new atom80 engines. I have an earlier version of this engine and the carb doen't have the preassure hose that goes to the crank of the engine. Do you know anything about the older version carb upgrade? Thanks

interesting about the new diaphragm design. I had a nirvana and Nirvana file off the T bit. I thought it was a bit silly since why change the design. But hay Walbro have done the same. Any way it seemed to work OK with out mod.

Andy, thank you for the video! I have a WB-37 carb, which I understand is very similar to the WG-8. I'm experiencing a bit of bog/fade at higher RPMs - so I have a question about the metering lever - and in particular - about how it interacts with the needle.
