Cleaning dark oxidation from a carb?

<< < (3/3)

58chev:
Here are the results of using Lacquer Thinner to clean my carb.

I kept the top and bottom plates from the 750CFM carb as they came out looking reat.

I used the fuel bowl of this 800 CFM carb.


Every cavity inside the carb had old wasps nests inside.
after a good 12hr soak in Lacquer thinner.


Here is a pic of both the 750 and 800, only very slight difference in the air mixture chamber??









Getting there, soaking most of the mall parts now..

Those two castings are not the same type, requiring a different air horn.  The one on the left is single MAB, so takes the later style top.....Cliff

ThanX, I will compare the two air horns again. At first glance they looked to be identical.

Cliff Ruggles:
I don't see pics of both airhorns, but those main castings do NOT use the same airhorn, and it's NEVER a good idea to swap parts around anyhow, for a variety of reasons.

It is a good idea to have all the oxidation and corrosion removed and the castings zinc/chromated, especially if the cleaning process has removed some or all of the original finish......Cliff

58chev:
So looks like I'll be hitting the swaps looking for one that is as close to the first one I have.

Yep, the air horns are different.
ThanX Cliff for pointing that out to me.  :)
