YES- The solenoid has a plunger (needle) that sticks into the Main Jet to block fuel flow. The idea being that when you turn off the key, fuel is shut off and the remaining fuel vapors are "purged" as the engine slows down. Removing these vapors means there is no fuel to ignite in the muffler (or hot carbon deposits etc. inside the engine) to backfire. Without the solenoid, fuel/air keeps flowing through the engine while the engine is slowing down after shut off. With the solenoid, just air pumps through. That's why your owners manual probably tells you to shut the engine off at higher speed. It purges any remaining gasoline fumes.

Hi, Jane. The computer seems to be working great. It's noticeably faster. I don't think that the mouse and keyboard not working was bc. of the RAM. One possibility is that I had put the USB devices back in any USB port - which I thought should be no problem - but may have been. maybe it was especially too much since there were 3 USB devices in new ports. The other possibility is that in getting rid of the dust bunnies - blowing the dust out with compressed air, that I got a bit of dust on the power supply plug/port. I'm not sure - but one place I googled (perhaps a cnet forum?) reported the keyboard and mouse not working bc. dust got into that area. They had unplugged the power cord - cleaned out any dust - and tried again. I did both. Unplugged the power cord and dusted the area again - and replugged the USB devices into the right ports. I also started by just plugging in the keyboard and mouse. Once I was up and running, I plugged the microphone back in. So I don't know what caused the temporary disabling of mouse and keyboard - but I"m pretty sure it wasn't too much RAM - just something I did when I was messing with the innards or replugging devices back in. All seems to be great now. I put it off forever too. I'm pretty sure that I went to Crucial's website (on the computer I wanted to upgrade) and let it scan the computer to determine how much RAM (and what type) it could use. If you haven't already tried that, I'd give it a whirl. Here's the link: http://www.crucial.com/systemscanner/ Let us know what you decide and how it goes. Good luck. Lynn.

I devoured this thread for months and finally went to Lowe's to look at these planks. When I first looked at them in the store I thought they looked so fake and cheesy that I almost gave up, but I brought a few home and set them on the floor. They looked good! It seems that most people have good results as long as they follow the directions really carefully and don't use professionals to install the floor. It also seems that the trouble comes when the climate is really hot or humid. But, just to make sure that we weren't the unlucky ones, I installed it in my entryway first to see how it would hold up on our concrete slab. I pulled up sheet vinyl and scraped off the remaining mastic, used the Henry's and it went down and stayed. I am a dog walker/pet sitter and we board dogs, all different kind of dogs, at our house and we needed something durable and easy to clean and this has fit the bill. I installed it in our entire downstairs myself. Everyone loves it and thinks it's either wood or laminate and several neighbors want to put it in themselves. I've noticed vinyl flooring everywhere now, including high end stores. Thanks to everyone for recommending this flooring and for the terrific tips. Here are a few of my own: 1) Definitely prep, prep, prep the floor. I scraped up mastic and glue from the carpet pad. I didn't use adhesive remover because one site I saw said it may soak into the concrete and interfere with adherence. The key is clean, dry and smooth. 2) The instructions on the box and the Novalis website recommend the self-stick tile primer. It is a must - it goes on really thin and dries clear in about half an hour. 3) Take your time when laying the tiles and get them as tight and straight as you can. 4) I found some walnut wood filler that I used in some of the tricky spots and it worked great. 5) Definitely let the planks sit in your house for 48 hours before installation. 6) I ordered OOPS! Painters wipes which Novalis recommends to remove excess adhesive. They also recommend them to remove the white "scratches" which Novalis calls scuff marks. I found that the wipes didn't work on the scuff marks, but time does. They eventually wear away. 7) I didn't use a rolling pin, but did baby steps on the tiles once they were down. There are a few that I missed and they sound funny. I have not had any scratches from dog's nails, but we did have some from broken dishes. It's not as noisy as laminate, but it is hard - almost like walking on concrete. I love this flooring and am so glad to have put it in. I am a middle aged woman and did it by myself. I took my time and did one section at a time and it came out great! Here is a link that might be useful:

Another idea...kind of like jterrilynn is suggesting, I think. I realized we had left out a 2.5" filler after our counters were in. I needed every last inch I could squeeze out of the open shelves above, but didn't want them to stick out past the counter. My contractor built this narrow cabinet that tucks under the counter overhang and is topped with butcherblock with slots for knives. Having the built in knife holder had occurred to me early in the kitchen planning but then just seemed like too much trouble, but it's turned out to be a great addition (and I think it covered the goof-up pretty well!) I also considered having a wine rack there, but I didn't have enough room. This is the best pic I have right now. Sorry-it was really taken to show the floor.
