Im not saying i screwed with my float levels, because i didnt

I bought a car that came with a sterling carb on it. It wouldnt run right when i got it (vac leak) i replaced every gasket that could possibly cause a vac leak last night and i still havnt stated up the car (waiting on drying rtv from intake freeze plugs). I did however cycle the key to get fuel into the carb. It seems that my float levels are both 3/4 up the sight glass. Now, this could just be a fuel pressure problem (right?), but im not positive. I set the fuel pressure to 3.5 but with inconsistencies in regulators and gauges i cant be 100% sure its there.

My question is this:

If the float levels are screwed up, can i just take floats from a parts carb and put them in this carb? I know the ones in my spare have never been touched, so they should be perfect still, right?

 

thanks for all the help!

 

You could swap the floats over but it's not a guaranteed fix. There are a few different sizes of float which use different measurements between the float and air horn, to attain the same fuel float level.

3/4 up the glass is okay, it will be a little rich but I wouldn't worry too much unless you are having problems. Also you will want to check the fuel levels in the sight glass after the engine has been running for a while to get an accurate measurement.
