[Ea81 Hitachi Rebuild -any Pointers?]

Had my twin Hitachi carbs rebuilt recently in Melbourne Australia by a carby specialist who knows his stuff.

Ive got an ea81 true twin carb model with the twin exhaust port heads. Fully rebuilt, wasnt running well till I had the carbs done.

If you find someone who knows their job, Hitachi carbs can be made to perform very well !!

Engine as well; fully recoed and have just had the carbs recoed. Running like a dream.

Yeh, thanks for that. Have tried Ausubaru but just thought I'd try further afield as well. No great dramas really; its running very well now after having carbys fully reco'd this week.

I mean the original box. Running with some universal chrome /foam air filters at the moment. Just seeing if I can locate an original box for quicker warm ups.

Can't locate an air cleaner for twin carb ea 81 motor anywhere in Australia.

Have you got any suggestions as to where I might be able to pick one up?

I have had a twin carb ea 81 motor with the d- shaped twin siamese exhaust ports fully rebuilt. Has had a "flat spot" on hard right hand turns from the start. Otherwise has been running very well. Now done 5000 km. Borrowed a compressor and have blown out all fuel lines; replaced fuel filter; fuel pump appears to be have no problems. Installed an electronic dizzy with the rebuild but had to set it way off the timing marks to get it to run. New dizzy cap and rotor. Decided to go back to the old points dizzy today. No improvement, except that the timing marks line up again.

Sprayed some carby cleaner around and it almost stalled when I blew it near the throttle shafts. Any thoughts...can these be replaced or rebushed? The shaft between the two carbys that the accelerator cable connects to, which then accuates the throttle shafts also has a fair bit of play in it.

What do you reckon.....

G'day there.

Ive got a late 83 ea81 series wagon; they are 1.8 litre. I'm pretty sure that it is called a DL wagon.

[Anyone Know what happened to ausubaru fourums]

Havent been able to get it since last friday. Phoned Tasbrat, who was the only phone contact i had; he has not been able to get on either. Something about their web service provider going out of business. Feel very disorientated without the daily fix of Ausubaru chat.

Right hand drive ???? What line of reasoning are we following here ???

[rebuilt twin carb ea81 hesitation on RH corners]

TomRhere; The bowls are on the left hand side when viewed from the drivers seat. have checked the site glasses this morning; both levels are pretty close to the dot.

Nipper; The coil is mounted on its side. I will try a spare coil to see whether this has any effect.

Thanks guys.

Hi there,

Have just rebuilt a twin carb EA81 motor. It is running very well except for a slight flutter/ hesitation on right hand corners. Some suggestions have been electrical; others fuel supply. A much earlier thread on this site sounds similar and relates to fuel bowl float levels. Any suggestions greatfully accepted.

Yikes 4mm.... Is that for each head or the total for both? If it's the total amount for both, then I would try using 2 headgaskets for each head.

 

As for having a spacer laser cut, there should be someone at that shop who can take a new headgasket and create a CAD drawing based on it. Where I work, we do things like that, every now and again.

 

Its 4mm total. I'm having some CAD drawings completed at the moment. 2mm aluminium spacers should be cut next week. This thread originally posted to see if anyone in U.S.A already had a set of CAD drawings. Two headgaskets wasn't suggested by my engine rebuilder. Would they seal properly?

[rebuilding ea81 twin exhaust port motor]

The problem is that the heads have been severely decked and the inlet manifold overshoots by about 4mm. I can get some aluminium spacers laser cut, but need a CAD drawing of an EA81 head gasket. A colleague on the ausubaru site suggested a place called CCR rebuilders in the US might be able to help; does anyone know of them?

My motor rebuilding has stalled until i can get a CAD drawing done.

Any suggestions gratefully received.

welcome to the board

 

well it could be because your bowl is full of fuel instead of being half full/empty and for webers there is a guy down in Oz that rebuilds them and also rejets them for our uses IIRC his s/n on here is cameron so might check the members list and find his profile for more info to contact him with

 

and for adapters you should be able to find them matter of finding out where you can find them Down under

Thanks for the reply. I will try and contact cameron about webers.

If the bowl is full of fuel, what effect does this have on carby? why is there an indicator level? suppose it is to do with flooding

[Sight glass in Hitachi carby]

Hi there from Melbourne Australia,

I have an '84 DL wagon and have swapped a recently reco'd Hitachi carby from another vehicle. It has tuned up well and runs well but I dont see the fuel in the sight glass. How easy is it to see? Do you see it only when the motor is running?

I am enjoying reading about the Weber conversions. Does it make a noticeable difference? What are the advantages of this conversion? I wonder whether the manifold adapter plate would be available in Australia?

Thanks for a very informative forum.
