I have an 83 vc resolute (2 doors that swing open) and last year I noticed some smoke coming out from under the top plate and the side wall occasionally. It wasn't the griddle but between the castings. I did the light thing and found many areas of light penetration on both sides. What is the proper way to fix this. Once it is fixed should it improve it's performance? Thank you for your input so I can learn how to do this.
