General advice for warmstarting by handcrank

Post by dykker5502 » Sun Apr 19, 2020 1:19 pm

I've recently bought a 1914 Model T touring, and I have just driven it a little bit (preparing it for MOT so no licenseplates yet).
When starting it cold, I turn up the mixture 1/4 turn, pull 2 times with choke, switch on the battery, in which case it actually normally tries a free start (!), and the it starts at next pull. After a minutes drive, I adjust the needle back to its normal position 1/4 turn in.
BUT - then when the car is warm after some miles of driving, I simply do not have the right grip of getting a similar easy start! My two other T's have starters, so it may turn over 5 or 10 times before it starts - not something I have done a lot of considerations over.
With handcranking its another story. You do not want to flood it as it make take its time to get it rigt afterwards, and neither try it to lean. You want to get the mixture just right.
The carburator is not a standard NH, but an aftermarket:

Not that I think it matters to the worst, it seems to perform very well when driving.
So what is the right approach?

I'm not so sure there is a "right" approach. Each one seems to have it's own ideocracies, Mine (a '23 engine, non-starter, 12V system) seems to like it when I retard the spark, give it about half throttle, give it 2 revolutions with the switch off and the chock pulled, then switch on battery. A 1/4 pull usually starts it (sometimes a free start). This is cold. After it's been warmed up, just retard spark, 1/2 throttle, switch on battery and giver her a pull.

I NEVER monkey with the mixture. I tried it and it caused more problems than it cured. I set it to the "sweet" spot and that's it.

I forgot to actually respond to your issue. In your procedure you do not mention where you have the throttle set. I'd try different throttle settings and see if that will make warm starts easier.

Same here. I was monkeying around with the mixture and all I was doing was fouling plugs.

I've found out through trial and error, where it likes the mixture and I leave it there. It runs a bit rough for about 30 seconds when it's dead cold, but after that it settles right in.

I find that after I have a warm engine and it has been off for just a few minutes such as when I stop to get gas, I can retard the spark and open the throttle about 1/2 inch. I turn on the ignition and if I don't get a free start, I just put in the crank and pull up once and it starts right up. Do not choke or change the fuel mixture when the engine is warm. If it doesn't start right up, try turning off the key and open the throttle all the way and rotate the crank about 2 revolutions, then move the throttle up to about 1/2 inch open and turn on the key and pull up once. It will usually start.
