Dave,
Thanks for that info. That makes perfect sense since the switch is a three way switch. So, that would be for starting, running, and killing? 15 min is plenty. I'm going to buy a new tank today for good measure, so I may stick a 14 or 16 oz in there. There is no spring starter on this one, so I guess maybe that why the timing system? Like I said, the guy who put all of this together has passed away. I ended up with it. Thanks for the help~!!!
