Engine stalls.

The fuel filter is new. The gas tank was nearly empty the years I had the car stored in a garage. Filled the tank halfway one month ago.

Now out to buy hoses and a one way valve.

I will be back with the results during this week end.

this is what it looks like, not really sure of its purpose, but again, you can tie the choke open to eliminate choke operation as a cause for the stalling
