Thank you all for the replies to my lawn mower problem. I haven't solved it yet...basically not much time to try. I did clean the foam filter though it was pretty clean as i had cleaned it just about 3 mowings ago. I made sure the oil is at the right level and there is gas in it of course. I checked to see if I could see light through the little holes inthe gas cap. I didn't buy new gas. This is gas from about 3 months ago. That should be ok I suppose. if the sun shinnes toomorrow I'll get different gas. I read the manual and paperwork for it from the person who bought it. The manual is pretty useless since this is probablty the lowest brand WeedEater makes. I believe the engine is similar or same as an inexpensive Poulan. The engine is series 300 (noot even comes up on the Web. It's B&S model 9S502.I looked on the Briggs & Stratton website but could not find more info. I don't think this moower has things like a screw to adjust the engine speed. It doesn't even have a lever or slider to control speed or to choke (if that's where a choke is). Just the basic bar in front of the handle that has to be pulled back to keep it running. We spayed some carburator "stuff" in the air intake when I had filter off. I wiggled a spring in that area and moved an object (explanation below). I then put the filter back and pushed the primer button 5 times. It wouldn't start for me. The friend pulled it once and it almost started but it didn't. And there was a small puff od dard smoke for the first time. He thought it was worse than the last time and wondered if I had "done" anything else to it since last time he started it. Sooooo Now...I took a photo of the area under the air filter. Because there is a little spring there...and I am wondering what that spring does and if that spring has a problem because it has no tension on it. What makes the spring do whatever it does? I labeled my picture: Line #1 is pointing to the spring. I also labeled another part that has to things sticking out (but it all one part) #2 and wonder what that part is for? It is moveable but doesn't seem connected to anything. The photo I took is on Garden Web Photo galleries It's called Woman driver re: lawn mower. Link to the photo is http://photos.gardenweb.com/garden/galleries/2007/10/woman_driver_re_lawn_mower.html If anyone sees something wrong in the photo I would be interested to know. The friend may take the mower back. Thoigh I doubt that Walmart would do anyything about it since we've had it a couple months and it did cut the lawn about 10 times. I also wonder...firstt replier pastmaster mentioned that My old mower that hit the pole may be fixable. If I took off the blade and tried to start it...would that tell me anything? I figure the blade would be dangerous if it did start. If I wind the lottery I'lll buy a new mower. :) Here is a link that might be useful: lawn mower photo

Hello SmokeMaster, I understand it a bit :o) In fact I wrote a post today on my blog dealing precisely with a LED array I built myself from similar high power LEDs : http://allhydroponics.blogspot.com/2010/06/building-your-own-high-power-led-grow.html. Since the current rating of an LM317 (which is your voltage regulating transistor) is around 2A you will need to use a separate voltage regulator for every 1-1.5A you will be needing. Taking the voltage drop of your LEDs in mind you might want to hook them up so that their voltage drop adds a little bit higher than 13.6V. Like this : String 1 (connect in series) = one 3 blue 3W string + one 2 red 3W string = 14 V drop Use the lower voltage setting so that you run your LEDs at a lower and safer level. You can later increase the current through the LEDs by reducing the number of LEDs per array. You should then build the number of voltage regulators you need (one for each array) using your LM317. The datasheet for this transistor shows you how to build a classical voltage regulator. The link I posted on my blog article also shows you how to do this. You should then connect the voltage regulators in parallel from your power suppy so that each one gets its required current. At 13.5-14V you should expect each array to consume about 1A which is enough for the LM317 to handle. However you should install small transistor dissipators on them so that they do not overheat. I hope this helps you build your LED lamp. It is always a great project to do ! Make sure you check my blog article for more info and pictures of my array :o) Here is a link that might be useful: Everything Hydroponics

Zep516, Thanks for the link to Dells support for laptop that he has. I have download the driver for him and will transfer it to his computer via a thumb drive. He can then keep it as a back up file in case the problem surfaces again.

It probably would help though I am unfamiliar with the units you mention. One thing that sometimes works is to leave one Xenon bulb in the string. This sometimes ends the flickering.
