View Full Version : 1991 ProStar 190 no spark

Thanks for any help.
I have a ProStar 190 351W stock Prestolite distrib that won't start. I have fuel and air delivery, with OK coil output, but do not spark out of the stock distrib. I am told that any parts for the stock unit are not avail, and I am considering drop-in replacement with Mallory distrib YLM554CV. I ran fine this year without problems. Does anyone rebuild?

As an aside, on the starboard side on the rear of the engine, there is a covered unit with a red button on it. What is this and what does the button do? It does not appear to "click" or reset anything.
