'lo all,
<< Im looking for an answer too. My Lehman is really slow cranking in this
cold weather. 30 degrees. >>
I think you are possibly missing the most salient factor that is causing your
slow starting/cranking engines .... it is cold .... the oil and battery are
cold .... the oil is thicker (even multi-viscosity) .... thick oil takes more
to energy to allow parts to slip .... more energy required means more energy
consumed .... means larger load on the battery .... means a higher voltage
drop across all resistances in between the battery and starter as well as
lower output from the cold battery .... means lower power at the starter ....
means starter turns slower .... means less heat is generated due to
compression per second of time .... means cold block absorbs lots of the heat
generated that would normally go to start your engine .... means you have to
keep cranking until you get enough heat in the compressed air/fuel mixture to
ignite it. And, if you crank too long, your starter can overheat, burn out
and you get to buy a new one.
Yes, this is possibly over simplified ....
