Bing 64 Floats

Can you post a photo of what you mean by notched?

Option 1: Get a set of complete rebuild kits for the carbs, including floats, and rebuild them both. The idle air screws should match from side to side. Usually between 1 and 1-1/2 turns out.

Option 2: Send the carbs to a Rotax facility for rebuild.

I will see about the pics tonight. The floats that don't have any issues have the corners removed on one side of each of them allowing the floats to sit parallel to each other in the bowl. When you look at them installed on the posts you can see how they are form fit. The the other two are just small rectangular (brick) floates that sit at an angle to eachother when installed. They are actually binding when I fill the bowl with gas and bob them up and down. It is also the side that I am having trouble with. I just hate paying 50$ each for maybe 2$ worth of floats. Everyone needs there cut these days. Even in the experimental market! I already have all of the other parts that I need, I think I am going to get out the dremmel anyway and see if I can shave the corners off and see if they will still float! Just wondering if anyone else has tried it.
Thanks,
Dave

I'd go with new floats. The walls on them are usually pretty thin, shaving - even if it did work, could be a point of failure in the future.

The floats should sit at a slight angle to one another. That's how they are designed to fit. If your's are binding, you need new floats.

"Shaving" them with a dremel will ruin your $50 floats.

I tried to post pics of both types of floats three different times with no luck. I found floats thru Spruce and Spec for $90 including shipping. I am going to notch the ones that I am replacing and stick them in a mason jar for a couple of weeks to see if they will saturate. I guess It is a known problem because I can only find the new notched style.

The float part number listed is 861-184, and per the LEAF catalog page 103 it looks like the current part has a non-rectangular shape to them. They list by the pair for $107.25 (page 117).

Mine are the rectangular floats and work fine at an angle to each other, with no binding. There must have been an update at some point.

my advice. buy two new floats. the flat sided ones are the old ones. there really isn't anything wrong with them. but I did replace those on my old engine. reason, they sunk. you take and modify your float and it will sink. they have a coating on the outside, disturb that and your screwed. back when I bought mine they were 50 a piece. as far as the settings between the carbs, put them all the same. you have two separate engines in one. if that gives you a clue. no need to buy their fancy carb kits. but the orings inside on the jets and stuff and gaskets are important. get those. needles. yes buy those and the arms, they wear a hole right where the needles ride, get those. it will cost, so open the wallet. if you put on K&N filters, don't put their oil in them. it will cause things to run rich, ask me how I figured that out. the K&N's will work just fine with no oil. If you clean them do like they say and don't use them until they sit and dry real good. good luck.
