Is it still dying after running for a minute?

Still runs very rough unstable
Expert:  Marty replied 1 year ago.

Previously you said it was dying after a minute and I felt as though you were lacking fuel. I said that if you could keep it running by adding ether I thought you had a fuel flow problem. If it stays running now but runs rough I would check the compression and check for vacuum leaks and pull one spark plug wire at a time and see if you can identify which cylinder is weak.

Do you think it could be a weak cylinder? The engine has low km?
Expert:  Marty replied 1 year ago.

You would have to rule that out first. You should always start with a compression test to be sure you have even compression on all cylinders.
