Stop in for a cup of coffee

We did. We took it for a short drive to see how she runs. It was a little rough at first. Didn’t want to stay running but eventually it got there. Not sure if it was the gas since it had been sitting all year. There is an exhaust leak that needs to be fixed. Next weekend we plan to take a longer drive. We are hoping to take this to Vermont at the end of the month.
What is it I am not sure 38 GM?
