Was looking through the SNL-G503 and noticed that early die cast carbs have a call out for a sight glass on the fuel bowl.

Specifically:

AW PLUG, sight level GM-2196082

For use on CCKW Prior to chassis No 321078).

The cast iron carb also has a bolt on the fuel bowl, buts it called a PLUG.

Does anyone have pics or identifying marks that would help locate original carbs? I guess post war civilian GMC 270 and 302 carbs will power a CCKW, but anyone got any good dope and CORRECT early and late carbs?

It is just what it says it is, you can take it out to look in. CCKW ain't in just one manual, you gotta go to one that tells U all about the Carby.

Why were you using the G-503, it won't tell you anything.

Simple typo.. and I had just done some posts on g503.com.

Good catch... at least you read my post

You're welcome. Wouldn't miss it for anything. I am having fun soaking up MV knowledge. I am learning all I can so that I can take a Chevy 4X4 steering wheel to the nursing home and mount on my bed and make Chevy 4X4 noises. I am having trouble double clutching, I keep hearing dishes rattling when I let the clutch out too fast.

Actually that sight plug in the parts list is a float level checking plug, fuel will run out if float is set too high.

I went through the SNL for the carbs, and found that there may be two variants of the die cast carb.

PNs: GM-2103965 being superseded by GM-2135998

Also, the fuel bowl seems to be another part that is superseded:

GM 2143816 Bowl, Fuel, Carburetor assembly (superseded by by Bowl, GM-2198543).

If ANYONE has what they consider an original or NOS carb (early or late) PLEASE send a pic to dealine@tm9-801.com so we can compile what is and isn't a CCKW carb.

I have an ID disk on my die cast carb.

Outer part number (GM PN) 2135998 inner number 9778B (Zenith PN).

So I evidently have the 'superseded' carb assy as per the SNL, and I have no PLUG, Sight Level.
