Flooding! What flooding?
You know I'm not even sure why I'm posting this thread. Maybe it's to inform some people that rotaties can in fact sit up for months on end and not have any problems with re-starting/flooding if properly maintained.
A little back ground. I've recently rebuilt the engine in my S5 NA vert. Since the rebuild, the Fd has been put on the shelf for a while so I could do lots of driving to run in the rebuilt engine. Actually the Fd sat up for 2 months. While it was down I decided to replace the longitudinal arm suspension bushings with some solid Jim Lab Nylon versions I picked up last week. Then I did a fuel filter relocation and added an aluminum shifter bushing (the bushing I should have done years ago).
Anyways since I miss the Fd, it was now time to drive it again. I put the key in the ignition, cranked it over, and the engine fired right up without hesitation. The rpm's shot up 3k as usual. After five seconds, I immediately shut the engine down. I wanted to see if it would actually flood on the re-start. I cranked it over again and it fired right back up. Hmmmm interesting I thought. This time I let the engine run till the AWS ran it's course like I always do. That lasted about 25 seconds. When the rpm's drooped, I shut the engine off again. Finally I cranked it over one last time to see if it would flood and guess what, if fired right back up again without any fuss. So now the engine has been started up 3 times with-in 30 seconds after sitting up for 2 months with no signs of any flooding at all. Keep in mind at no point did I ever touch the gas pedal. Now the amazing part is this in all on an original engine that has 103,000 miles.
Some of you may be wondering how this possible (especially with this high original mileage). I simply fun quality fuels (89 octane Texaco w/ Techron). For the last 5k miles I've been doing an engine flush before every oil change. Lastly, I do the water steam cleaning method 2 times a year. All these things do a great job at fighting carbon build-up which keep the internal seals nice and loose. Now it's time for a compression check.

I've never had a problem if I remembered to re-start it right away. Flooding seems to happen when you start it, shut it off cold and park it for a day. Then try to re-start it.
You're also in TX.. warmer climates. Try doing it at 40 degrees F.

Well I tried again yesterday when it was 55 and is still didn't flood. My engine now has 107k on the clock.
