    Thanks, Dave. I will get on that test in a few minutes. I havent had ANY performance issues. My main reason for cking the vacuum was to see a reference reading before starting to tune the carb. The wild oscillations surprised me and sent me down this path. i will ck and try all tests recommended. AND.. i will keep all advised of my results and whatever issue i do find. back to the garage for a while.
