OK! I have a 455 rancher that I could not find the fuel problem on. I changed the primer and fuel line and then bought a aftermarket carburetor for it, same thing! It will start to prime and then you can hear it sucking air from inside the venturi and it gets bubbles instead of filling the bulb. I have by pasted the whole saw and ran a gas line into a pan with the same results, bad check valve in the new carb??? Thanks, I don't want to put a 45acp thru it.
