Hot engine starting
 

OK this is the question?.

6V carrier, Ford V8, will not start when hot.

Yes its that old V8 problem,
but whats the best answer.

I've been told give it half trottle when trying to start.
Never pump the trottle
No choke.

You guys in hot Aus must have an answer.

Barry i(in a hot London)

Poor a little room temp water on the mechanical fuel pump. SHould help almost immediatley.

Have you determined the cause?
 

Playing with old flat heads a number of thoughts occure as to what is causing the poor hot start.

There has been some discussion on this in past take a look at

Lots of good comments

Hot starting V8
 

Barry,
I have found with my T-16 here in WARM Arizona, that I need to hold my accellerator pedal down all the way, not half throttle, and it starts after just a few turns of the motor. Works every time for me. Rod

I agree with you...
Right to the floor..don't pump...you are flooded...Holding it to the floor opens up the carb to straight air mix which leans out the starting combustion fuel/air ratio...
Very much like natural gas fuel air combustion ratios..
Between 7%-14% gas to air ratio for ignition...
Ahhhhh...my old flat head school days....
Vapour locking at the fuel pump will only occur when ambient air around fuel pump is excessive..
This flooding situation will happen anytime,even at -10F,as long as the engine is hot....
Jordan...don't pour water on your fuel pump when it is cold out...pour whiskey in the owner....

Gee Alex I never new you had a "FLATHEAD" lol Sorry to hear it mate:)

Flooding
 

If its flooding itself then firstly check your needle valve and then the float level.
if the float level is too high it will flood real easy.

Lynn what in the heck you talking bout man?? How does the Floaty Have to do with the Heat coming from the pump??? I think you better Skip instead of Jumping LOL BIG MIKE

Thanks
 

Thanks for advise.
Are LP carriers 12v or 6v like English and Canadian carriers

Aust. LP2s and LP2as were originally 6 volt. Nearly all vehicles of that era were 6 volt.
Larger vehicles and radio equiped vehicles were generally 12 volt.

I thought this Thread was on "Over heating" not Flooding???? are they both intertiwned into one thing? please explain.

You appear to be the first person in this thread to mention "over heating" Ford v8's are real prone to flooding when hot.
Vapour lock is separate problem. When you have a column of petrol sitting between the fuel pump valve and the needle valve, and its hot in the engine bay, the fuel tries to expand.
If the needle valve wont hold it, or the float level is a bit on the high side, then petrol piddles down into the manifold, and floods the engine.
I believe Barry is trying to find out how best to clear it. or to get it started from an "engine flooded" situation.

I separated the two problems on my first posting..

Alex, Alcohol in the veins increases the risk of hypothermia (although i'm sure it does dull the bite of the cold). (Brain fade)
