Starting six when cold, Strange phenomena Options

[gereed75]

Car seems to start normally when warm

When cold (40 degrees or below) I can get car to start hesitantly after numerous pedal pumps to prime. It begins to run when motoring starter but as soon as I release key to run position the engine suddenly dies abruptly as if being switched off. I can eventually get it to run after very persistent motoring on the starter until it begins to clear and will finally run in the run position .

It just seems that the run/ignition circuit is significantly weaker in the run position than in the start position, like maybe the run contacts are high resistance or bad ground??

Are there two separate contacts in the ignition switch?? One for run and one for run/start??

Can the switch be opened and checked/cleaned??

Thanks.

I have 40 IDAs and have never had that experience. When sitting for weeks, (empty float bowls) or very cold it might take 3 tries to get it running, but after it does start it holds its idle. Having it start like a Toyota is not realistic with carbs but that doesn’t sound like your issue.
