Blasting carbs...

From my '43 G8T...

First, how it came off the truck.. gack!







Then it got the plastic media treatment in the cabinet....





Taken apart & blasted again...











& today it it got the soda treatment to remove the brown staining...

 

Nice !!

Rat

 

didja save the hard candy coating?.... its a dessert topping.... its a floorwax! man, that looks GREAT in the after shots.

 

Now all you need to do is caustic clean it and reapply the zinc dichromate finish which is there to protect the carb from corrosion and chemical damage .

 

I live in the Mojave, nothing corrodes here, I have steel engine mounts I beadblasted 15 years ago that look lke they were done 15 minutes ago

 

Looks good, but I hope you took it all apart and did the inner galleys after removing main jets, power valve, p/v plunger, air bleeds, spray bar, idle jets, check valve, etc. That all needs to be soaked not blasted.

 

That's next, I was just cleaning the gack off. (the manuals arrived yesterday)

& I'm not sure about this zinc dichromate finish theory, the brown stuff would wash off with dish soap, coatings don't usually do that..

 

I just rebuilt that exact carb. I bolted it back on the truck as the light waned.

It is on a '51 F1, with a flathead six.

 

Rebuild kit available anyplace?

 

Yes, I got it at the local speed shop, Lee Automotive, in Alameda CA, but I have seen it online in a few places.

I found the rebuild kit online by searching for the carb model number, which is on the side, not the year/make/model. The year/make/model search did not yield any results for a whole kit, for whatever reason.

Edit: I managed to remember, somehow (at home now): The kit is Standard Motor Products Part #28, Hygrade Jiffy Kit for FORD #8HA-A.

Rock Auto has it: http://www.rockauto.com/dbphp/x,catalog,154,partnum,28,d,STANDARD_MOTOR_PRODUCTS_28.html

...but you should be able to find it locally.

 

What is this plastic media you speak of?

Would soda do the same thing?

 

here ya go! http://www.plasticmedia.com/

 

I have two kinds of plastic, the finer acrylic & the larger urea. Soda will do the same thing, but that shit gets all over the yard & it's reusable so that's the last step after the plastic etc.

Having said that....*proper* blasting soda is a lot coarser than the stuff I get from Stater Bros etc..

 

Perfect! that's saved some time
