do not look down the carburetor while your trying to crank the engine. It could backfire and shoot fuel, or worse, ignited fuel into your face. But if you want to risk it, wear safety goggles. This is what I would do. If you disconnect the line from the carburetor and crank the engine (catching the fuel in a jar) to check for fuel to the carburetor. Re-connect the fuel line and try cranking the engine over. With the engine NOT running. Look into the carburetor and open the throttle linkage by hand. Just before the throttle plate are wide open, the power piston should shoot extra gasoline into the venturis or throttle bores. If it is totally quiet, you should hear it and/or see it. If the fuel line screws into a fuel filter fitted to the carburetor base, the filter may be in backwards. Another thing you can do is crank the engine over with the throttle wide open. Do this for about 6 seconds, wait and crank the engine again with the accellerator all the way down. Now check you spark plugs to see if they're wet. If they are, replace your plugs with new ones and try starting the engine. If your plugs are dry, and there is no gas entering the throttle bores, you have a much more serious problem, indicating improper procedure of carburetor re-assembly. It could also be such a simple thing as putting a gasket in the wrong way, or using a wrong gasket on re-asembly.Is there anyway to check my carbureter on my 1986 chevy truck its an edelbrock .?
I take it it's a four-barrel? You should be able to look down in the carb while having someone crank the vehicle over and see a spray of fuel going down into the engine. If not, you may have a problem with the float level and needle-and-seat assembly. Take it back to whoever rebuilt it and have them check the float level.Is there anyway to check my carbureter on my 1986 chevy truck its an edelbrock .?
If I'm not mistaken, it is a duplicate of a Q jet. Take the air cleaner off and look inside at the front venturi's with a flashlight. While looking, reach over and pump the accelerator with your right hand. If you see gas being squirted, then you have fuel to the carb. If not, your float may be stuck. Sometimes a couple of whacks with the plastic end of a large screwdriver to the front of the carb will free it up.
