can anyone tell me the diameter/gauge what the push-pull rod would be on carb linkage ?? much thanks

Hi Anne, Here are a couple of pics of linkage I 'm doing....
The rods are shafts from broken # 80 drill bits. .0135 or about 34 guage.

i can't believe what my eyes are looking at , holy cow , Randy , you really should do a video on this type of work , i for one would buy it in a New York Minute

Sorry Anne, No fancy video but I do have a build thread for this project in the Truck section , On the workbench Pickups.

Try electric guitar strings. Any name brand X X L gauge high E string, available as a single string about 32" long, with a nice brass grommet at the end.

This is an area where actually "fudging" on scale accuracy is almost a must, given that 1/25 scale is rather small to begin with. For those who are metrically challenged, 1/25 scale is .040" to the inch. So, for example, if a push or pull rod for carburetor linkage in real (1:1) life is 1/4 inch diameter (.25") then in 1/25 scale that comes out to just .010", which is about double the thickness of a sheet of high quality paper stock--awfully small. But, if one uses say, .015" or even .020" for such linkage rods, the size is still small enough so as to be believable, and it will still add scale realism to the project.
In the model railroad hobby, there are suppliers offering fine brass rod stock in such small sizes. Check http://www.walthers.com/ for brass wire--their stock STARTS at .006" (six thousandths of an inch), really small.

Yeah , If you look at Randy's wip thread you will be inspired to do things you never dreamed of ! Of course actually doing them is another thing .
The brass rods Art mentioned are the easiest to work with . Also most hobby shops have piano or music wire down to about .015" , it's a lot stiffer than brass but stays how you bend it . You also need a good set of wire cutters ( don't use sprue cutters ) .
