davem1111 2,156 #2 Posted June 12, 2023 Is she running badly? What are the symptoms that suggest a valve adjustment would be the fix? I'm curious because I have a 1987 312-A that isn't running well. Cleaned and adjusted the carb, new spark plug, fresh gas, still not right. So I'm thinking I may need to look at the valves also. Share this post Link to post Share on other sites
