Jets are usually stamped on their sides which the way the Ford mounts them on the bottom of the bowl they can’t be seen.

The jets are test flowed and marked for flow against a standard which is actually pretty close to their drill size in inches. With a small drill set you can get pretty close by inserting the smooth side of some bits till you get to the go, no-go condition.

Not marked at all

 

[1953bigblock]

Still don't help me out what size

 

[RWENUTS]

Certainly doesn’t help if we don’t know what carb it is!
pic helps.

 

[1953bigblock]

It's a new carb with no marking on it Did you read the first thing

No marking at all nothing on the jets nothing on the carb

 

[RWENUTS]

That’s why the request for a pic!
on another forum recently a guy asked for info on his Holley 2300. A pic revealed it to be a stromberg ww carb.
so, pics help.

It's a ford 2100 2bbl I been working on cars for 46 years I know the difference

I presume this is the import version of the 2100. I’d expect that the 1.23 inch bore version is probably going to have around a .068 jet plus or minus a few thou. Like I suggested taking the round end of some small drill bits. I’d expect something in the range of 51 to 48 which would be dimensionally .067 to .076 inch.

The throttle blades are 1.55 can't tell you what stock jets are in it

 

[1953bigblock]

A stock 289 is 47 to 50 jets I have couple of junk carbs

 

[1953bigblock]

A c8tf ay is a carb number for a 1968 f100 360 - 390 has 54 jets in it

After 46 years I'm surprised you haven't learned how to be more courteous to those who you're trying to get FREE information from .

 

[1953bigblock]

Ok guy if people would read the first part instead of just reading just a few then be no problem but I guess you know it all

Please keep your comments to yourself

 

[RWENUTS]

Yup!
The first part!
Ford 2bbl!
I read that!
Doesen’t give us a clue which carb. There’s likely a dozen possibilities.

 

[1953bigblock]

Ok I give up

 

[1953bigblock]

 

[1953bigblock]

Just like this one

 

[2old2fast]

If its " just like this one " then why not look up the specs on this one for yourself ?

 

[1953bigblock]
