I have an '02 Taurus with 85k miles on her that I just bought. Today when I was checking something under the hood I noticed this metal line cold and dripping with water...
I had the air on but turned to the position of arrows pointing out of the dash and floor vents only. The defrost or a/c function was not selected. It seems to be doing it consistently. I haven't traced all the parts of this car's a/c system yet but I don't know of anything else under a hood that turns cold and sweats. Why would my compressor be working when it's not selected? What tests should I run?
I've never done this before but after reading a few thread I decided to check my valves for the first time and to my surprise it was much easier than I thought.
My bike is a 2005 Sp 500 HO.
I first pulled the seat and the right side panel off, and that's it! It wasn't too bad to get at.
Next I pulled the spark plug out and removed both the head cover ( 8-8mm bolts)
then the side cam cover (5-8mm bolts).
Also remove the plug in the recoil cover (14mm bolt) to see the timming marks.
Next I turned the engine over with the pull cord untill it was at TDC of the compression stroke.
The best was to tell that your at TDC of the compression stroke is to rotate the engine until the
timing marks are parallel to rocker cover gasket surface.
The cam sprocket locating pin will be facing upward directly in line with the crankshaft to camshaft center line.
Now fine adjust by looking into the timing hole in the recoil cover and line up the upside down "T" on
the flywheel into the center of the hole.
Now using a feeler gauge, slide the .006" (.15mm)blade between the top of the valve and the bottom of the adjuster and adjust accordingly
To adjust, Loosen the locknut (10mm) and check clearance with a feeler guage. Clearance should be .006" (.15mm) for both, intake and exhaust valves. Turn the adjuster with a stubby flat blade screwdriver untill the proper clearance is achieved then tighten the locknut (5.8-7.2 ft. lbs) while holding the adjuster in place with the screwdriver. Re-check the clearance with the feeler guage one last time and re-assemble the covers (72 in.lbs) and plugs.
The only thing that i noticed was that I had to clean and silicone the side cam cover other than that I found the whole process rather simple.
I'd give it a 4 out of 10 on the skill level scale.
I hope this helps!

posted a while back - it was running at one point - I have all the plastic shroud off - it's down to frame and engine now
-fuel pump: when line from petcock is attached, no fuel comes out other side to carb; the line to the carb is open (can blow through it); I thought when I cranked engine that the pump would spit out fuel on other side but it does not; I removed fuel pump and opened it up - diaphragm looks good - but internal areas had lotsa calcification build up - I cleaned this out and dried it good - the clear plastic pieces (?diaphragms) aren't broken - the spring w/ steel ball on end moves freely; am putting it back on tomorrow; but can anyone answer about the pump? isn't it supposed to pump fuel through it... to other side... to carb? puzzling
-along with fuel pump: I replaced petcock 3 weeks ago (gas tank had rusty fuel in bottom - cleaned it out prior to new petcock); when I turn petcock arrow NOT to on or reserve, fuel comes out of line; when I turn it to on or reserve, fuel doesn't come out; puzzling
-I don't know what's on back of fuel pump - it's a valve that has a hose coming out of it - looks like it goes to engine/carb - I haven't traced this out yet - what is it?
-can squirt gas on air filter and engine will run for 2-3 seconds then stop - fuel in top of carb (under diaphragm) does same
-it likely needs carb rebuild - will get to this - but something isn't allowing fuel to get from fuel pump to carb
-I THINK it has a mikuni model x carb - diaphragm is ID 26mm OD 68mm - hard to find inexpensive diaphragm, I guess because it's a model x
-last thing - I replaced solenoid due to old one clicking; I HAVE to be charging the battery or it won't start/turn over - battery just goes dead; but if charging, it'll turn over nicely; i'm guessing it's a bad battery
-any help appreciated - I've never owned an ATV before - inherited this beast from grandparent in-law
Hi, I have just purchased a 2002 Yamaha Kodiak 400 I think, the vin has worn off and I have located an engine number I think it is J312E-004674, could anyone tell me where the engine number might be please

AL righty I did some trading around this weekend and ended up picking up a few 4 wheelers for cheap. I ended up with this one for $500 in it total and well the guy told me it dropped a valve. I haven't really messed with it at all. But this weekend I am going to try and start working on it some to get it running before winter time frame. So what I am asking is a couple of questions.
1. First off where do I start I tried pulling the pull cord and could not get it to move at all.
2. I need to get a service manual for this 4 wheeler where can I get it downloaded for free?
3. what do I need to look for and how do I go about this really. I do have experience with 4 wheelers but this one is a little different to me than others because its a V2 and I have no clue where to start internal on the engines. Most of my experience is on the outside portion of troubleshooting on theses wheelers.
Please no smart butt answers as i am new to here but just wanted opinions on where to start. Please and thanks wink:
Hello, well back to where I was last year with this carb. Took my 250 to the mountains for the first time this year and blue smoke, too much gas again. I can't believe that this carb gives me this much trouble. Seems like the choke is stuck but the cable moves freely. Anyone else ever experience this issue? Do you think a new choke cable would maybe resolve this?http://www.quadcrazy.com/atvforum/images/smilies/arghh.gif
OK it was the choke. Put on all new cable and plunger and she is running 100% again. So now the question is, is the carb getting worn out where the plunger needle goes in the small hole and when I use the choke the needle end doesn't get lined back up with the hole?? We'll see how it runs and now that I know what the issue is I can always pull the choke plunger out and reinstall if I start having this issue again.
