*****up-date*****

 

LOL!!!! of all the stupid things to miss ... I just needed a new mixture controll solenoid .. for now I have the old one taped in place :D hope Subaru doesn't want $9,000 for a new one :rolleyes:

 

**********************************************************

 

well, I got a Chilton, so you already know half of my problem o.O

 

I'm trying to figure out where the adjustment hight is for the float level on my EA-81 carb from my '85 brat ... the book says the hight should be 0.435-0.492 in. (11.5-12.5 mm) and the diagram shows what looks like inverting the fload assembly, and making the first measurment from the choke chamber to the top of the float, but I want to make sure this is right ... the written instructions refer to "the air horn?!" I have no idea what that is :drunk: and the diagram also seems to show some other measurement with the float fully extended down (with the valve fully opened) just wana make sure I do this right before I put this all back together ... also ... the sight glass for the float bowl ... where should the fuel level be judging from the sight glass? the middle? :confused:

I just got the info on the float adjustment, but now I'd like to see an exploded view of the carb ... anyone know of a good place on the web?

The float level was about in the middle of the sight glass in my carbd ea81. Im sure there is a diagram that might help you in my manual, but i cant find it! When i do, ill post a pic of the page if you want.

You`re right,air horn is another name for the top of the carb.

 

Correct on the 2 adjustments as well.Float height and drop in that order.Fuel in the middle of the glass.

thanks u2! I really thought that was correct but just needed to get it confirmed ... I have rebuilt alot of motorcycle carbs, but all these hoses make this kind of carb sorta intimidating :eek:

 

I got it all back together now ... taking a break to eat and rest then finish up and see how she purrs! :D

 

I need to visit the auto store again tonight to get new belts and the second fuel filter that's near the rear passenger side tire and then I will see if I get some decient mileage now :banana:

 

I have been getting bearly 20 mpg and my poor brat struggles to go more than 75 on flat road ... I hope my cat isn't plugged too :dead:

Ok ... I replaced the rear fuel filter, and thought maybe I discovered something ... it appeared that it was on back-wards ... and yet it still wants to have the mixture screw waaaay out ... anyone know what kind of mixture screw it is? air or gas?

  • Author

all fixed now ... it was just my $#%@#!! fuel mixture control solenoid!! too bad I didn't realize that B4 I tore the carb apart:rolleyes:

 

oh well ... at least I have a clean carb now and brand new fuel filters
