On the last West Coast Tour, my Star wouldn't start without priming it through the spark plug hole. This was true even when gasoline was dribbling out the carburetor intake. Once started, however, it ran fine. Roger showed me how to hold my hand over the carburetor intake to start it. That got me thinking it might be a vacuum problem.

And it was. The copper line from the intake manifold to the vacuum tank was split. This led to the engine not having enough suction at start-up to pull the gas through the carburetor into the cylinder. Once started the higher RPM's created enough vacuum to over come the leak.

This is the second time that line had split. Both times at the vacuum tank. I'm thinking of switching to a rubber hose. Does anyone have experience with this?

Hey Vince;
Is the line coiled from the bottom of the vacuum tank? I was told that that is why they coil the line several times to help keep the tension off it and keep it from splitting. Just a thought.

Yes, I coiled it after the first time it broke. It broke at the flaring so maybe something got nicked when I put it together.
