RE: Hot starting problems on '84 UR-q

My 85 ur-q has a similar issue. It starts just fine when stone cold or when hot,
but does not start well (or at all sometimes) if partially warmed up. Pulling the cold
start injector plug will almost always allow it to start immediately when this
happens. As pulling the plug stops all cold start injector enrichment my guess
is that the injector is operating when it should not be and making the mixture far
too rich. Mebbe the cold start temp switch is bad? Bentley is very confusing and
incomplete on this system as are the dedicated ur-q trilogy of factory manuals.
