carb spitting

When i first picked up my olds, it had a 260 in it. i'm trying to get it running until I can finish the build on my new motor.

The original carb was in bad shape, so I bought a re-built carb, it's a Rochester dual jet 2 barrel.

Same problem as the old carb, It will start and idle sometimes. Other times when you crank it, it will make a "spitting" sound and spit a mist of fuel directly vertical out of the carb.

Is it something wrong with the timing?

Also, there are several vacuum lines not attached, I attached all I could that came with the car, but there are at least two vacuum connections not attached on the carb, and the crank case breather isn't attached either.

If the car spits a fuel vapor directly up and then dies you may have a timing issue not a carburetor problem. Is the engine fully tune up? If the open nipples are 'sucking' air when the car is running then they are creating a vacuum leak and you need to put a cap on them, this could cause your first problem too.

The engine has been sitting for quite some time. I changed the oil, spark plugs, wires, filters, and re-built carb.

There were no hoses attached to the factory intake, they were probably lost or misplaced with the previous owner. I will check to see if those lines are sucking in air.

Thanks for the reply

I just hope my idea helps. I could be way off base though. Let us know what you find out.

I think you're right on. It's gotta be a timing issue.

I tried to rotate the distributor, but I couldn't get it to budge, there's gotta be a set screw on there or something.

Turn your balancer to zero, and your #1 cylinder to top dead center. You will have to pull the #1 spark plug to see the piston.

Then pull the cap, and let us know what cylinder the rotor is pointing to.
