I have an 85 GL with the Hitachi carburator and it has a choke issue


Recommended Posts

Let me clarify that I am not that familiar with carburators as a whole and am even less familiar with the Hitachi on my GL, however it wont idle on cold starts unless I sit there and give it gas until it's warmed up, from what I know this is an issue with the choke?

It could be the little tab on the end of the spiral spring is broken. 


A few things to consider. 
 

You could just deal with it and work the pedal.

Could take that choke housing apart and likely see the small bent tab at the end of the spiral spring will have broken. Then either find another from a junkyard or an enthusiast. 
 

Could get the Weber kit.

Yeah, I was just wondering if it was common and an easy fix, I planned on replacing it with a 32/36 anywho

Thanks

Don’t go the Weber, not worth the trouble! 

If you have an auto choke it should work on initial start up. Try double pumping the throttle before turning the ignition on and starting. Don’t touch the throttle pedal. 

If all is working well it’ll start and have high idle until you tap the throttle again, then it’ll drop the idle speed down and open the choke a bit more.

Yeah the choke doesn't work at all, but I'm curious as to why you think the Weber swap isn't worth the trouble? A lot of people say it's a much better option than dealing with the Hitachi

Speaking for myself it’s about not giving up on the Hitachi which to this point gave the vehicle how many miles ? Probably over a hundred thousand. So the Hitachi is proven. It’s when age creeps in and folks bail out. 

And I have experience with Webers but not on Subarus. 
 

Weber is a solution but you’re spending a bit more money and you’ll want a choke cable as they don’t have the convenient automatic choke. But if you’re still curious and have the extra money talk with those guys. I can’t really speak for putting a Weber on a Subaru.

From what I can tell Weber sells a bolt on kit for the 32/36 progressive and it has an electric choke, and from what I hear it can be a bit of trouble to get on but it's worth it because you can actually adjust stuff aside from the idle air mix

There are many ppl that go down the Weber route and have loads of troubles with them - or just chew a whole lot of juice running with one. 

Give the hitachi a good service with a new kit (keep the old bowl float valve - the ones in the kit are never correct) and go again. 

You’ll find there are two camps in the Weber world - those that continue to run them and manage them to keep them going and those that revert back to the hitachi carb. 

Personally a rebuild kit was far cheaper than a Weber so I went that way with my Brumby and I have no regrets. It runs awesome now!

Alright, you've convinced me, I'm gonna rebuild the Hitachi with a kit from O'Reilly's and maybe swap the auto choke for a wire

Thanks for your support
