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) |

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 http://www.mapleleafup.org/forums/sh...ght=vapor+lock and http://www.mapleleafup.org/forums/sh...ght=vapor+lock Lots of good comments Cheers

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....

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.

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.

Big Mike
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.

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