ok so i picked up an old wankel from someone. the guy said that the injector o ring was shot and bogging out so he decided to pull apart the intake manifold and such and of course didnt know how to put it back together. so no i am cleaning up after his mess. im piecing everything back together, but im curious as to what the air bleed does? it fits down in the injector hole and the injector sits on top of it, but its not a good solid connection... is there something im missing?

can anyone help me?

As far as I know the o-rings should just seal it and that's that... I'm not sure though since all the ones I've seen have been old.

The air bleed breaks down the fuel from a large spray to more of a mist. In other wards reduces the concentration of fuel.

but what about when i install everything??? it feels like the injector isnt sealing to the top of the air bleed?>?? i replaced all the o-rings on the injectors but not the ones on the air bleed.... think i will have issues??? i am also thinking about removing all the old vacuum lines and the rats nest.... but all the info i can find is for the 12a and the 13b carb. how do i remove the rats nest on the 13b fi-egi? i wanna just eliminate all i can to simplify things....

Do you have the thick grommet at the bottom of the injector?

Also do not mess with the rats nest on the SE!

and yes i replaced the thick grommet on the bottom of the injector, but it just rests on top of the airbleed.... i also replaced the little plactic cylinder on the injector nozzle... it just doesnt go down as far as i think it should....

They are not going to snap into place. Even when the fuel rail is bolted down on them, they could still twist a little. The fat grommets at both ends should hold them firmly in place.

Your fuel rail is what keeps the injector in place, not the air bleeds.

The SE rats nest are for other functions unlike the carb'd models. It is easy enough to hook up the vacuum hoses.

If you do not have them hooked up you will have all sorts of issues!

Yep, he's right. The rat's nest on an SE is there to perform all kinds of vacuum functions to keep the engine idling smoothly, so even though it's not pretty, it's all there for a reason.

EFI is a different animal than a carbeurator which is the same basic mechanism that you have on your lawnmower, unless of course, your lawnmower has electronic fuel injection...

As to the air bleeds, these function as 'atomizers' for the spray coming out of the injector and help to get the flow of gasoline evenly distributed in the intake air path. If you just shot a squirtgun with gasoline into the air path, it wouldn't run very well or make very much power, since the gas must be separated as much as possible in the air for smooth power. Ideally, if you could separate every molecule of benzine from one another, it would be a very efficient burn inside the engine - the air bleeds help with this.

As an aside, air bleeds were designed as a band-aid for poor atomization. With the newer crop of injectors that have better atomization, they're not necessary anymore.
