Is there one shop that stands out for overhauling a hitachi carb worth sending mine away to?

 

Oh, and don't get cheeky and tell me Mr. Weber! :D

I would think the cost to weberize would be the same as having someone else rebuild  the hatachi .

Way more expensive to convert to weber.  I don't really consider them an upgrade.  At least not until they've been tuned correct.....which very few are.  You can easily lose gas mileage, develope idle and driveability issues, and fight run-on dieseling.

 

 

The rebuild kit is ~$25 and it's easy to do yourself or pay a shop I charge $75 one hour labor.  No shop should charge much more than that or your getting ripped off.

 

Hitachis are easy.....there is nothing to lose inside except one little ball at the bottom of the accel pump but reassembly is so obvious no way to screw it up really unless you break something...

 

As long as you don't have too much throttle shaft play, your hitachi will be great after a rebuild.  Spend the 25 bucks and do it yourself.  Make sure to remove the emulsion tubes and blow them out that's the biggest issue they have.

I have been told that Webers can be problematic to get through emissions, which is a consideration here.

Yeah, everything post-1966 has to pass. Lots of cars in the Mens Mall just because of bad emissions components. I have a 1973 GMC Motorhome with a 455 and a Quadrajet and it has to pass every year (unlike cars and trucks who go every other year).

96 and newer out here in NH. And it's not even a sniff test, it's visual and a plug into your diagnostic port. Both easy to fool.

Two bottles of methel hydrate and a tank of Mohawk 94 ethanol and 90 % more likely to pass that day shhhhhhhh don't tell anyone the hitachi ran fairly lean anyway so should not be hard to pass as long as its working right

I am new to this forum, but I have a rust-free '84 GL that has been to two places in Madison WI who cannot seem to find a new carb. The baby has sat for over a year, so I wanted to check here....and low and behold it seems like you can fix it...correct? Please e-mail me at jofunk@hotmail.com if you are interested. I can get it boxed up and sent over. Or, the second shop was telling me to just buy a new one. Doubt those exist. Looking for some advice & help here if  possible. Thanks!

+1  Many if not most people go to the Weber because they are unnecessarily intimidated by the Hitachi rebuild or have false preconceptions about it's worth which are perpetuated on this forum by people who don't really know. 

 

In reality, tuning the Weber correctly requires as much, if not more, attention to detail than rebuilding a Hitachi.  Individuals that don't want to deal with learning enough about carbs to rebuild the Hitachi generally probably don't get their Webers dialed in correctly.  I do consider the Weber an upgrade, but only if it is properly tuned, otherwise it's really just a band-aid that is an order of magnitude more expensive than the Hitachi rebuild.

I putt SPI on my 81 ea81 it loves it and 12 years in no problems at all gets better mpg more power and drivability I love it took me one day to convert it. Intake wire harness distributor ecu maff I used one from 86 gl for parts but any spi 85-94 will work
