'85 EA82 hitachi carb rebuild ?s


Recommended Posts

1. how do you remove the throttle chamber from the float chamber?

2. how do you remove the power valve?

3. how do you remove the plug to remove the idle mixture adjusting screw in the alunminum chunk infront of the carb?

 

Hi,

 

I've had a few of these apart. What I did was ground a few screwdrivers down to fit. All the jets, air bleeds, power valve, so on and so forth.

 

That plug for the idle mix screw, I just drilled it out. I think a quarter inch bit was the last bit used on it.

 

Throttle chamber from the float chamber, large screws on the t chamber side.

 

hth,

 

Doug

#3 involves some specalized tools for drilling..taping..a new seat for the air mixture screw and spring that will have to be gotten from somewhere..even professional carb rebuilders have a near impossible time to get these carbs to work ..and then of course the float has to be checked and adjusted..no room for error here

Peter,

 

I may be missing something here. That aluminum chunk? After I drill the thing out I disgard the whole mess. I use the screw and spring, put some blue locktite on the threads if it's loose.

NO locktite of any kind..even if that screw is loose..it is suppose to be that way...the pro carb builders use a "carb dyno" to set the carb up..but this "setting up" is for a new motor...so when you get, for example, the carb back from the re-builders,.. further fine tuning adjustments can be done if needed...perferably with an air/fuel analyzer..I don't know your car or cylinder compression..but generally speaking, the older the car is, ...some adjust will have to be made even out of the box..the rebuilt carb I bought from "tomco" specificly states this Edited by Petersubaru

Well Peter, I'm the builder. The modifier. I only use what works, what is the point otherwise?

 

Sincerely,

 

Doug

 

Edit: Crystal ball on the table. I don't know the future, Peter.

 

P.S. I'm cheap. Really.
