[alfa] Gas issues

[alfacybersite <acs@xxxxxxxxxxxxxxxxx>]

How do people manage to get dirt in their gas tanks? I've never figured 
this out. Yes, I fully understand the situation if a car has not been 
started for a number of years and what that does to a gas tank, lines, 
carbs, etc. But assuming the car has been kept running fairly 
continuously for most of it's life, where does the dirt come from?

I''m not sure this is the case anymore but in the "olden days" sediment 
would build up in station's underground tanks and when the tanks ran low 
it would suck up this sediment. Might be wrong but willing to bet there 
are government people whose job it is to check on such matters today. 
Okay, doesn't count on that little filling station on that back road on 
the way to Nowhere, but for most stations, I'd guess they're pretty 
seriously regulated against water and dirt mixed in with the gas they 
dispense.

Not saying people shouldn't have filters. If I had a GTV6, I'd pull out 
the tank and have a peek inside. If any sediment, have it cleaned then 
put an inline filter Before the pump and change it every few years.

I just removed the 40 DCOE's from my Alfetta GT. They've been cleaned 
twice since I installed them in 1980 but had never been able to get the 
brass bolt / cover off the carbs' filter. This time I removed the bolts 
/ covers Before removing the carbs. Both were absolutely pristine as was 
the tiny well in which they reside as was the bottom of the float bowls. 
Couldn't even find any sediment by running my finger around the bottom 
of the bowls.

Why do I get the feeling that those who have dirt-in-the-gas problems 
also are the same ones who have green "mold" around their battery's 
terminals?

I think I know the answer to this one, but why do many of the, 
especially, older cars not like to start when cold and need more gas to 
do so? I'm assuming it is in pretty good tune. You have gas, you have 
fire in the hold, why the extra gas? Why is the engine unwilling to wake 
up? Gas + spark (should) = fire - hot or cold.

The AROSC encourages boy and girl racers to come to their time trials in 
the "cold" months by telling them the best times are almost always made 
when nippy out - as opposed to on really hot days.

Okay, I'm sure they don't start their runs with cold engines, but the 
implication is "cold air is good".

Please don't say, "Too cold is not good, just as too hot is also not 
good, but the engine temperature must be "juuust right".

Does the water passage in the 4-cylinder inlet manifolds heat or cool 
the fuel mixture and why? And if it is to cool it, then back to the 
original question.

Yes, you are correct, I did not set the world on fire (so to speak) in 
high school physics.
