I know in -20F weather, trucks start hard. But how come when I let it sit a few days, then go to start it, it starter is real slow, then slowly speeds up until it fires up? Almost like it builds momentum to fire.
Just a general question to get your brains working

i'll agree with that. i know the battery warms up as it draws. when it's really cold i'll turn on my lights for a bit to warm up the battery before i draw on it with the starter.

Ok, I figured it was because something was warming up, just didn't CLICK in my mind that it was the draw on the battery. It's too cold to think. It makes since now, on a smaller scale, 9v batteries get extremely hot when connected to something tiny.

as you all know iam not an enginer or a sciencetest, iam just an old guy. my idea is that there a few things that cause an engine to be hard to start when it has been setting a while.
1. the oil has drained out of the bearings
2. the carburtor has lost the gasoline
3 the bearings in the starter are dry. so you say arnt the starter bearings all ways dry? no, most starter bushings are what is called oil-lite bearings, that is a poures bearing materal that holds oil and when it gets hot the oil comes out to lube the shaft, invented by chrysler.
4. power loss in electrical cables when cold..
5. the battery has less output when cold.
6 what little oil is in the bearings is much stifer.
7. gasoline evaporates much slower. on carbuarted engines i learned a trick years ago, it had an electric fuel pump i would run the pump to get gas into the carb then i would pump the gas 3 times, then wait 30 seconds. it would allways start very quick.
just my ideas after driving for 44 years

Aw, come on fellas. Moe ain't that old, he's only got one year on me. When we first started driving the horses were under the hood and not in the barn. Course, you young fellers were probably nothing more than a wet dream during the muscle car era. :spank2: :thatfunny

i road a dinosour to school with fred flintstone. when i started driving the price of gas was 1/3 of the octane. my third car was a 1965 chrysler 300L, if you made one panic stop from 80mph that was the last stop you made for the next hour, the brakes got so hot. no to start my 300 i had to feed it two vws. i just loved having a FULL size car, 16.08 1/4 mile totaly stock 4200lbs. the 300 would blow cadys off like nothing, but i had a time with the pontiac grand prix gs, but the non gs i could beat easy. we build a 59 ply wagon with a 392 hemi. my dad kept raceing GTOs but couldnt beat them. i finaly told him you cant give away 1000 lbs and beat them. enuf living in the past
