Re: tracking down ticking noise

I would try spraying GumOut down the carburetor throat with the motor racing on fast idle. If the noise changes the likely culprit is sticking valves.

In the old days before reproduction parts the old timers had success pulling the valves, polishing the stems with crocus cloth, and cleaning the guides with a wire brush on a drill.

When I faced these problems I always recommended a complete valve job and refused to replace only the lifters due to the high failure probability.

The polishing method might be more suited to your situation given it will not affect the lifter pre-load.
