I am trying not to open too much of the carb for now, I am going to put the carb from my other car on.
The carb was a professional rebuild, so I don't want to change anything. If it proves to be the carb, I don't want him to come back to me with "Well you changed this". So I am reserving that.
I did open the carb, examined the jets, all are clear. A burr would happen all the time, and I have not found any debris.
But thank you for your input.
