One of the Best Videos I have seen on the Rotax 912 Engine Carburetors. Straight Forward and very informative.

Nice job Darrell.. Not a bunch of useless youtube jibber jabber, but straight to the point good info! Be sure to make a carb rebuild video or prop balance video, if and when you decide to do those jobs!

Well explained and clarifies the process perfectly. Will share

Great new owner information

[@portnuefflyer]

I've been doing it that way for 15 years or so, and always felt a bit guilty about using the mechanical method! Good to know it's a more accepted method than I thought! I have a MacFarlane vernier throttle, and will crack the throttle open just enough for a .24 feeler gauge, just because that size is "custom bent". I get a faint amount of drag on the first one, than similar on the second one, works for me,.

Thanks for the vid. I've got a 914 and have a question on the sync process. If you use the ferule to adjust the closed position and not the idle screws won't that adjustment get screwed up if you have to adjust the full open position? Rick

[@darrellwitham832]

There is a lot at play here between the ferule & stops for both carb sides. The idle screws are used to reduce or advance low end RPM, the ferules adjustment is to only match the timing between the two carbs so each side bottoms out simultaneously. My description about adjusting low end idle is not entirely accurate in the video, I'm talking about a very slight difference within the adjustment, the idle screws are the primary means to adjust the RPM.

Great vid. But I couldn’t get the name of the aftermarket floats. What was it again?

[@hugoburns6379]

Great video, thanks for making. How have the Marvel-Schebler floats held up over time?

[@darrellwitham832]

Spot on for weights, very pleased with these over OEM type.

[@paulstevens1264]

A very good video - issues well explained but Id like a little more detail about how to clean and check condition internally!
