While taking a close look at my carberator on my 37 I see my metering rod is on the top side of the power valve lever ! .if I set it up under to lift the rod , as under power on the close side the metering rod bottoms out. It acts as though the metering rod is 1/8" to long. The metering rod no. Is. 75-450 and the main jet is a. 120- 185. Does anybody know what should be in here. This carberator was rebuilt by someone and is clean as new. I have rebuilt gm quadrajet carberators but this has me stumped Thanks. Dave

I have found out that the rebuild on my carberator is fine, the metering rod is held up by a spring and when the motor is running it is held down with vacuum on the power valve , when the excelerator is pushed the linkage lifts the metering rod. A good article on this is on you tube for the carter aw1 carberator on mikes parts.

iPad,
By any chance, do you mean the Carter single barrel WA-1?

If so, this is a very widely used and reliable carb.
