Setting Float Drop on Briggs 206 Carburetor

[@fatpugnyc]

Great video! Looking forward to the next one. Great if you could have a close up angle.

[@PointKarting]

J jk noted on the close up's, something we are working on getting more of!

[@billricker1591]

Is there any consideration given to the motor mount angle when setting the float

[@PointKarting]

Hi Bill! Really, really good question! We do not consider the angle of the engine at our shop, although we do hear this from other racers. In our minds, once fluid is traveling through the carburetor, this system is under pressure. It is minor, but it is true- wherever a fluid such as fuel or air flows, there is a pressure differential. With this in mind, it is the pressure or cycling of the engine that is more important to consider (at least to us) when setting the float height. Now, with that said, we admit we are a karting service center and retailer, not the highest-caliber engine builders. So, with that in mind, I'd ask a few different racers and retailers you trust for their input as well. For us, however, setting the float height based on engine performance and metering has always been the way to go. We hope this helps!

great video. Is I have been draining the fuel out of the carburetor before driving home. I have heard that this can change the flow setting because it is unsupported by the fuel in the carburetor during the ride home. thoughts?

[@PointKarting]

Hey Keith! It's fairly unlikely that this would change the float drop setting, but it could as this would put some 'strain' on the float as it jostles up and down along the road. The little retention flange for float drop usually won't engage or bind with the float tower until it is always down at the bottom of the range, but if the bowl is empty this can definitely happen! I would strongly recommend keeping fuel in the carburetor (especially VP MS93) as it will suspend the float in fuel and prevent a chance of this alteration of the float drop. Really, really good question!

good video, hoping you'll put up a video on how to actually tune the carb. i'm completely new to messing with carburetors, so i need all the help i can get.

[@PointKarting]

Don't we all! We will work on putting out some videos on how to tune different elements of the carburetor. If you'd like to chat with us regarding immediate questions prior to video release, reach out to us at [e-mail]

[@dollarbillsportscards5455]

Please consider a close up of doing the work and the parts. Cannot see what you are doing.

[@PointKarting]

@Dollar Bill thank you for the feedback. We recently put together a 206 tuning guide document as well. Reach out to us at [e-mail] and we will send you a copy with more information!

[@joeburnes]

Great video. Consider increasing volume.

[@PointKarting]

Thanks Joe! We will work on our volume, I think folks will be happy with our upcoming projects!

[@daddychaos9837]

Any way you can show a close up of the different tabs....I'm not totally sure which one to adjust

[@PointKarting]

Hey Chaos, we are working on some new videos on the topic! In the meantime, the tab in the 'middle' of the arm for your floats adjusts your float height. The small tab on one side (on the reverse) of the float set that is near the uprights adjusts your float drop. I hope this is a helpful comment for the confusion! Thank you again for letting us know what you'd like to see in a remake of this early video.

Can the idle be adjusted and what is the target idle rpm?

[@PointKarting]

Hi Lorenzo - Yes the idle can be adjusted on the Briggs. For most racers we suggest setting the idle at 1,800 RPM. The manual suggests 2,000 RPM, so either setting will get you fairly close. The idle adjustment screw is on the side of the carburetor, and is the larger of the two flat-head screws. You can observe how it works by removing the air cleaner and watching how adjusting this screw moves the throttle slide up and down in the carburetor to understand its function a little better.

[@PointKarting]

@A J sure! We actually developed the manual internally - email us at [e-mail] and we can get you the manual you would like!

[@zt9984]

Random question: any idea what size o-ring is required for the bowl drain screw on the PZ22?

[@PointKarting]

Hey ZT - This is an actual part that Briggs sells - here is the link on our site: pointkarting.com/collections/lo206/products/lo206-carburetor-assembly (part no #25) I'll measure that at our shop as soon as I get a chance and reply back on this!

[@PointKarting]

ZT - The O-ring on the main bowl drain (the M8 brass fitting at the very bottom of the bowl that also can be used to change main jets) is 15mm OD, 11mm ID, the small bowl drain screw the o-ring is 5mm OD, 4mm ID. I hope these measurements help!

[@daddoesthings]

Great video! Just what I needed

[@PointKarting]

The Noob Woodshop glad you found it helpful! Let us know if you have more Briggs 206 questions!

[@EddieMunoz805]

Can I use this engine for riding riding town on my mini bike fucking around or is it only for racing

[@PointKarting]

Eddie Munoz awesome question! The 206 Is used in all sorts of lawn kart and “fun kart” / mini bike projects - we have a customer working on that right now actually. It’s so durable it would be great for a mini bike.

[@EddieMunoz805]

Point Karting I’m getting one setup already but I heard it will over heat if I use it like I want too that’s why I asked my question if it will only be for racing or all around messing around and riding around town

[@PointKarting]

Eddie Munoz nice! Any build pictures? The 206 definitely runs hot, as it is air cooled. But, on a mini bike that’s exposed to the air, and considering the engine is designed to move around go karts, quarter midgets, mini dragsters, I’m fairly confident it’ll handle the weight and strain of a mini bike. Ultimately, there’s only one way to find out! Following along with these videos to set up your 206, or any components you need for your build is the best way to ensure the engine is running properly. Likely the thing that would overheat around town before the engine does would be your clutch, depending on how the engine is used.

[@TheSpeedracer1982]

hard to see what tabs you're talking about.

[@PointKarting]

Hi Jason! Thank you for your feedback, we apologize for the far-shot, note that this is one of the first videos we made, we are in the process of starting up producing more videos consistently and this is one we want to re-make! Reach out to us anytime at [e-mail] if you have any questions on setting your float height and drop!

[@lorenzodibacco1812]

Thanks
