Im working on a 2014 Toro XT6715-2070 149cc engine where its having issues on warm up. After starting it will run well for about 30 to 40 seconds or so then start to stumble for about 10 seconds, then runs OK for about 20 seconds, then goes back an forth doing this for about two and a half minutes then just starts to run well from then on. After its ran for about 6 minutes it still does not fully open the choke butterfly. The carb is a new OEM carb and I pulled the fuel filter to eliminate any possible issues with fuel restriction. The air filter is also new. Iv had this on other identical mowers and have not yet found a solution. The choke is one of these that mount directly the muffler and is the size of about a fifty cent piece that mounts flat on the muffler. It does not appear to be adjustable in any way. if I hold the choke rod open fully I do not experience this issue. Im sure Ill see this again so if anyone has any information for me that would be most helpful.

A lint free alchol wipe. The kind they use for cleaning an injection area for insulin. I also have a special rubber rejuvinator in a small bottle and its wiped onto as much of the rubber feed rollers that you have access to. HP does offer exchange programs on some printers. My office Jet is huge, color and black cartridges are about $60 for the pair, and after 2 years a paper guide broke off when the print head hit it. I sent back that base part and they exchanged it. It had a 3 year service plan which is now passed. Once it craps out, its history. Its sometims cheaper to get a new replacement than to get the old one fixed. No one will repair an HP inkjet as they are not user serviceable, and there are no legal repair sites. HP just exchanges them at a cost. The site below has a spray can with a long thin tube. You need to remove any paper lint as well as any 'shine' on the feed rollers. Don't attempt to rotate the rollers as they are on a geared shaft and can damage the gears. Run a few sheets of paper though while you spray the rollers. Just print blank pages so the print head stays put.

I thought I'd report back for people who are still looking. I ended up getting the Canon Pixma MX850 (after seeing the review at pcmag.com which suggested that there were substantial improvements over the earlier model (they were not directly comparing it to the mx700, but rather a recent MP??? model. Nevertheless, it sounded like this 850 was better than what came before (the details about how skip my mind, but I know in readin it, it seemed worthwhile). I had someone set up the Canon on Friday. It is big (and as Jane said, it's attractive and seems commercial in quality). I LOVE IT. The software is not bulky like HP, and it was easy to connect the printer to my desktop, my daughter's, my husband's laptop and my laptop. I can scan documents and the wonderful lcd display will walk me through simple steps. It asks if I'm scanning from the platen or document feeder, if it should be saved to a pc or faxed or emailed (I believe those were the choices). Then you can choose which computer to receive the scan (that computer must be on to receive it - otherwise I think it could be sent as an email attachment to be loaded on the computer later), and whether it should be saved as a pdf file or jpg. There are other formats for saving it in as well but I haven't tried that yet. There's also a way to optically capture the text and turn it into a text document which I think can be edited (for those without the expensive Acrobat Writer which allows editing of PDF files but costs a few hundred dollars). I know some of the above is very simple and naive, but I've included for folks like myself who have no idea what they were looking for. It easily prints in color or black. It has a duplexer. I'm not sure I'll care that much about printing two-sided documents, but I love the either of feeding 2-sided documents in the ADF (auto document feeder) and being able to copy or scan them without standing there and changing pages. That was a huge factor for me in getting this over the MX700 which doesn't have a duplexer. At first I hadn't considered the convenience of copying and scanning 2-sided documents by loading the sheets in the ADF, pressing a button and walking away. That's convenient. This printer is also remarkably quiet. I was used to loud functioning from my HP PSC 950 and didn't realize printers could be so quiet. I could even carry on a business call without interference. I'm thrilled with this machine (which Dell has for $239 - best price I found). Even my husband who saw no reason for obsessing about this choice is amazed at how much functionality and ease of use is packed into a $240 machine. When he saw what it did, he assumed I'd paid over $500. Lynn.

I think the main printer - the first one I mentioned is working better. Perhaps I managed to "hit" the right button - at least for now. Thanks anyway. Bejay
