"I retired yesterday after 45

"I retired yesterday after 45 years of service with my company. Today is my first day of retirement. I hope this means I will have even yet more time for boating, which includes working on the engines.

I ran across what seems to be a pretty good introduction to the use of vacuum gages in engine trouble shooting that might be of interest and help. I am a real proponent of their use although my use has been limited to determining when I have a spark plug misfiring or fouled. I hope you find the link useful.

"Chuck....thanks for the link.

"Chuck....thanks for the link...vacuum gauges have been around forever and they are still quite useful even on modern cars and boats...most of the older gauges also doubled as fuel pressure testers for the older diaphragm type fuel pumps...As pointed out in the link, they are great for spotting a clogged catalytic converter. Very non-invasive as the doctors say. They are not useful on super high performance engines with high lift cams and lots of valve overlap as these engines dont produce a lot of idle vacuum and when used in cars, often require some type of assist for the vacuum brake booster.
Congratulations on your retirement, stay busy, stay healthy and do all the things you wanted to do when you didn't have the time. Best of luck and happy new year!"
