Peter, good to hear from you! Have no fear, the beer brewing is going strong.

Unfortunately, the 300TE isn't. I was too busy to play with it today. What doesn't make sense is that unplugging the idle control valve, idle drops to 500-600 rpm. Plugging it in raises the idle rpm to 1300-1800. So it's not failing wide open, which would indicate it's stuck. Instead, it's opening wide open when plugged in and closing upon being unplugged.

I haven't had a chance to replace all the rubber yet, but will. When I sprayed WD-40 around the rubber, I didn't detect any engine speed increase (of course, that was before I disconnected the idle valve, I don't think the hoses went on as tight as they came off).

It's running fine without the idle control valve. It idles at 500-600 rpm. Is there anything wrong with running without the idle valve? I will keep trying to track it down, but I want to know if it's better to run around at 500-600 with the valve unplugged, or at 1300-1800 rpm with the valve plugged in until I get it figured out.
