Definitely worth getting a knowledgeable person to take a ride with you, and/or let you ride in their car for comparison and diagnosis. There are a lot of things to look for and experienced eyes and ears will get you closer to the problem before you tear things apart. If there's a Model A Club chapter near you, try to reach out to someone. You might get some great insights, and probably make a new friend! Good luck
