[DeTomaso] Subject: Why is it hard to start cars that have been

Sun Jan 16 15:08:43 EST 2011

Chuck,

I have the turbo version of that engine (TSIO-520G) in my 207 and have never seen that issue, but I don't think I ever started it below freezing except when sitting only for a couple hours.  Thanks for the tip though, I'll remember that if it ever happens.

On this original problem, was this with a dual-plane manifold?  I can see one side of a carb having a bad passage and running 4 cylinders with a much richer mixture until it warms a bit.

A Cessna 207 (powered by a Continental IO-520 6 cylinder opposed recip) I
use to fly back in the 70's was prone to plug frosting. When the engine was
cold soaked it would frost the plugs over after a failed start attempt. If
you didn't successfully start it on the first attempt, the residual water
vapor from a few pops would frost the pugs. The only way to start it after
that was to use a Herman Nelson (heater) to pre-heat the engine. If the
airport did not have a Herman Nelson we would run the engine periodically to
keep it from becoming cold soaked. In the warmer months the temp was not low
enough to frost the plugs and it would start like a champ.

Those Continentals were good engines but took some care and some PT (pilot
technique) to keep them going.

I've never seen the same phenomena in a V-8 but I don't see why it couldn't
happen if seriously cold soaked. 

I have seen water vapor inside of a 289 distributor cap (after a water hose
failure) keep it from starting. Spraying it with a drying agent cured that
though.

I don't see how condensation could stick around on a spark plug for more 
than one exhaust stroke? That is a LOT of air blowing past that spark plug! 
Think of the sound the air makes coming out of a spark plug hole when you 
crank an engine.
