I do not recall seeing any of these, and the only part of the plug to touch 
the wire was the tip, not even the treads.  So, not going to concern myself
but know I need to consider another method. ;)

Sorry to see you had trouble: must been hard back then.  Father mentioned 
having trouble when he worked in Long Beach in the '70's.  Has asthma so 
the smog and indoor smoking did not really help.  Could be the reason 
children still have trouble, including allergies.  I hope to remember the 
past so as we do not repeat it. ;|  The pendulum always seems so swing to 
the extremes. ;|

A bit amazing you could do that long of a ride.  Your commuting to work
is encouragement to bike to class, then to everything else that I could.
Now to the point I have two bikes, a cargo trailer, and rebuilt a '68 
Schwinn for my Sister, but even though she is a tree hugger will only use 
the car.  Got quite crowded in the dorm. ;) So, thank you!

I liked the bit more perk it had, and was a several mile per gallon 
difference in consumption.  However, if I knew it really helped with 
pollution, then I do it.  I have thought along the same lines.  I think
it is Brazil that is doing well with gasohol from feed grade beets.  I
have tried to set up the Squareback to run E85, but have not seen it 
here locally.  If I had the time and place, I try and make it myself which 
be a definite help to the environment. ;)

Thank you for the reminder, but chemistry was one of my favorite classes,
especially of the sciences.  Sorry, ;) but I just never got the mechanics 
formulas, but liked E.M.F. as related to the Unified Field Theory.  Guess it 
help if I understood better how Calculus related to practical life.

What about when the engine ingests water?  I would think it try and hydolock 
if too much water.

Interesting!  Thank you for the good explanation.  Can one still get a 
quality twist cap?  Mine is about twenty years old and all dried out, so
looks like I need to get another.  Be its third cap in its lifetime as 
far as I know: still have the one before it.


Thank you so very much!
