OK Ossie, going by the majority I'm going to give this a try either today or tomorrow when I get a chance. With a daughter getting married soon my free time isn't mine anymore! Without an O2 sensor nor exhaust analyzer, I'm not sure how to adjust the mixture. I used to use a vacuum gauge back in the day, but not sure that works on these closed systems. Still, I'll figure it out. I have two questions that seem to be sticking in the back of my head.
First, if the control pressure is too low, why does it run flawlessly? Because mixture is used to compensate?
And secondly, if the residual pressure is ok as Bob and Tony have mentioned, then why won't the danged thing start when it's warm?!
Thanks again to all who have chimed in
