Re: [AMC-list] AMC V8 Heat Riser

AHHH Eddie, I can tell you've never started a car in 30 below zero 
temperatures. or for that matter, 35 above zero temperatures.
That heat riser is of critical importance then. And yes, I continue driving 
my 70 Javelin right up to the first snows of the season, sometimes
that's as late as December. The temps can get very "cool" that time of year, 
here in the great north land.
With out that heat riser the car is almost undrivable until it it nearly at 
normal operating temperatures.
In even fair climates the engine will consume additional unneccessary 
amounts of fuel if the heat riser does not function. It's purpose is to warm
the fuel in the carburetor to help it atomize and to begin the process of 
heating the chole pull off coil as the engine warms up which also reduces
the richness of the fuel mixture.

Cooler climates, If you want a cold blooded animal until engine warm up is 
nearly complete bypass the heat riser, if you want a docile animal, that 
when well tuned,
(a nearly lost art these days, I mean tuning a carbureted engine) bypass 
that heat riser and stumble on down the road.....  if you know what I mean.

Armand
