OK, I see in the IPL that item # 238 (Briggs # 691843) is the cap you referred to. Thank you for outlining the part about "holds 80 psi". Now that you have confirmed what I thought you meant, I need to ask, is 80 psi, the pressure you are applying to the cylinder (I presume you have an adapter air fitting threaded into the spark plug hole) with an air compressor, or is the compressor SET AT A HIGHER psi........and 80psi, is all the cylinder will maintain? I hope you understand what I am asking but let me put it another way. While you have the source of compressed air connected to the cylinder, does the air compressor cycle on and off to rebuild air that is leaking off "somewhere"? If the air compressor DOES cycle on and off, but you don't have any air leaks in your compressor air hose or plumbing, then the air must be leaking out of the cylinder somewhere. An "air leakdown test" is not simply to connect air to the cylinder and see how much pressure the connected air compressor is capable of maintaining (on the gauge). An air leakdown test must really be done with a gauge that "measures the PERCENTAGE of leakdown, even a "good cylinder" has "some leakage". It is neccessary to determine if the "actual leakage" exceeds the "allowable volume (%) of leakage" An air leakdown test is also conducted to determine WHERE the air is leaking from (valves? piston or rings? head gasket?). So, your answers to the questions of just how you are achieving the "80 psi for 30 minutes" will allow us to get past that issue as you may well be getting a false indication of "health" from what you have been doing there with the air pressure. During an air leakdown test, you should be listening to for air escaping into the exhaust system, or the intake manifold, or into the crankcase. Of course, the crankshaft must be stopped at the correct position AND HELD there so it cannot turn when the air pressure is applied to the cylinder. To "listen" for escaping air, I use a 2 foot length of plastic tubing (5/16" or 3/8" diameter, at auto parts store or plumbing supply). Place one end of the tubing into the muffler or exhaust port (if muffler is removed) and hold the other end close to your best ear. Any air leaking past the exhaust valve will be heard through the tubing. To check intake valve, place one end of tubing into the carb throat (with throttle wide open) or intake port (if carb is removed). Air escaping past the intake valve will be heard through the tubing. To check for air escaping into the crankcase (because of piston, rings, or head gasket defects), take the oil level dipstick out and listen for escaping air coming from the dipstick tube, or you can hold a small "flap" of tissue paper over the open dipstick hole, if significant air is coming out of the dipstick hole, it will lift the tissue off the hole. Wipe off the dipstick hole before laying the tissue in place so it won't just "stick" to any oil. OH YEAH, please post here and ask Mr. Walt Conner to post his "cryptic" e-mail address so you can contact him for HIS instructions on adjusting the valves. Walt is one of the primary Briggs contributors on this forum and most times Walt's instructions are better than Brigg's. It would not be "proper" for me to "set you up" with his e-mail as Walt has his own way of handling that. However, if you search in this forum and find a post where Walt "furnished" his e-mail address to another member, I'm sure he would be OK with that. It's just polite and PC to "ask first".

So the problem does not seem to be the motherboard, you have a signal onscreen. Is the replacement motherboard identical to the one that failed? Did you simply pop the hard drive back in with the original Windows install on it? Do you have the CD that came with the newer mobo? (If not the drivers will be available online but expect slow downloads fro the Asus site if you use them) Have you tried putting the XP CD in the drawer and doing a repair to see if this will overcome the issues? Remember if you do this you will need to download and install every update and patch issued since the CD was created.

Susie, I have searched & can't find any Avast on it. I also went into the folders. I just did a search on this one & there is quite a bit Norton leftover on it still. AVG is on too & was working when I stopped using this one. I hope to have another one Monday if everyone would just get well..I don't drive (never learned) & all my rides are truly sick. Cat, I think I will try the XP tonite. I do know it has a LOT of problems & need to be started over..it is not worth spending $150 to do that. Nite before last I was trying to fill out a form to order something.. it took over 30 minutes to do it.. The cursor kept freezing plus it wouldn't scroll without freezing. Some on here can vouch for all the problems I have had. If I can get it running I can at least check to see if there is anything else I want saved. I tried to keep things saved as I knew this day was coming. Yes I know now the APC is probably why it wouldn't turn on but I don't think that had anything to do with the other problems. The XP took about 20 minutes to reboot.. this 98 is very fast doing it. Thanks, Dar

Called Tech Support and they had me do a system recovery from the hard drive. After I did that, it worked ok for a couple days and started giving problems again. I called TS again and was told there was obviously a problem with the OS. They promptly sent me a System Recovery DVD. I inserted the DVD and followed instructions. Although I was told that it would take about 25 min to do the recovery- 2 hour later I had to again call TS. The PC was in a loop- it keep giving the message to wait while it loaded the software-then it would restart and do the same thing again. But again the TS was very prompt in giving me instructions out of my loop and back to recovery. I now have the PC restored to original. Have restarted windows twice and all seems well. I guess time will tell. Though it is pretty frustrating to spend more time working on the notebook PC than playing (Or using)it, I will say that the TS was really great. I'm am really hoping that is fixed now, though. Thanks for all the input. Donna
