I have a 85 Buick Riviera which I just installed a Carburetor on. It seems to be working ok but having trouble getting gas up through the jets. I read up on others with this problem and said it needs to be primed with a eyedropper. Maybe I am a little dumb about this well it is only my 2nd time replacing a Carburetor. So my question is where on the carburetor is there a spot so small that you need to use an eyedropper to prime the Carburetor??
