The bottom half of fuel vent would not come out. What didn't you show yours coming out. I suspect I'll cut mine out also look for a replacement part. The video did help diagnose the problem and i thank you for that. I didn't think the carburetor had to come off either. Thanks for posting this video.

Bill there's a fine line between making the videos too long, and showing every nuance of the work done, so I have to make a judgement call on the content. As you saw with the disassembly process, I simply showed a quick "here's how it comes apart" vs. a much longer process of showing every step in more detail. I demonstrated, close up with the camera, how to remove the vent, and I explained what part of the vent I was leveraging against, and what part of the vent I was working to free up from the fuel tank. Seems pretty sufficient.
If you'll spray Kroil or PB Blaster in around that base, wiggle with a screwdriver like I show in the video, and allow that movement to get the penetrant to wick down in around that o-ring, you'll be able to leverage out the base, just as I show in the video, without damaging it, and without damaging the fuel tank. New OEM vents are available from many online sources if you don't have a local dealer. They're on ebay, all day long, for 16-20 dollars each, shipped.

I will now say that finally a power tool apart from cordless drills etc that a cordless blower will in fact do an excellent job and without any traditional maintenance. Bought my wife a Husqvarna Aspire Blower 18V Kit With 4.0Ah Battery and 2.5Ah Charger for AU$309.00 when our old faithful 2 stroke "heavy" and more complex "for my wife" to operate with confidence is absolutely fantastic. However this does not extend to saws or brushcutters of a traditional 45cc capacity. I have to confess that for real power and also long extended periods, the gas is still the way to go. Just my opinion. Cheers mate.

I completely agree. For the home owner, with occasional light/normal use, battery powered stuff from the top manufacturers is the best option. Gave my daughter and son-in-law the Makita 18v system last year: blower, and power head with string trimmer and articulating pole hedger. I also gave them a gasoline powered BillyGoat brand yard vac, which allows them/us, to do all the yard work and trimming, and then vac up the mess for a professional look when finished.
