Thanks guys. I drained the vacuum tank completely, cleaned the lower unit out and made sure the upper vacuum tank was empty. I cleaned the glass bowl and filter screen while I was at it, and put in a new filter bowl gasket. I then added enough clean fuel to allow the engine to start. I replaced the "new" gas cap with the original one, but first I checked it and made sure it had a good vent, which it does. So now I need to test it out. However, must wait till next weekend to do that. Will let you know how it goes.
Thanks!
Thanks!
