Q:Valves Knocking?
disconnect the positive battery terminal for a couple minutes. Other than taking it in to have it reset that is the most generic way to clear it. but it sounds like your timing advance system is not working.

Q:Symptoms of a bad idle control valve?
Could be.. Also could be dirty. Easy fix, remove the valve and spray carb cleaner in the hole.. Using a small brush, clean the bore that the valve rides up and down in. Also, inspect the valve while it is off the manifold. Harder fix: After cleaning the bore, replace valve with brand new one. Your car will have to relearn the idle after starting with the new valve or after you put the old one back in.. Start car, but do not put it in drive or give it any throttle until the computer has finished making adjustments. - Dave. (Long Island, NY)
Q:Help with a leaky valve..
If the leak is at the valve stem tighten the packing nut just below the stem, if leak is on either end of the valve tighten them with wrench also, if that doesn't work remove entire valve after shutting of water at main supply remove valve and take to hardware store to get a replacement valve, they will beable to tell you how to reinstall properly.
Q:how to check valve clearances?
Adam S, you're both right and wrong as far as needing to adjust valves. I changed 2 shims in 100,000 miles on my Kawasaki KZ1000, but my 1300 Kaw touring bike with nearly identical valve train needs checking and adjuuting every 6,000 miles or so. Go figure. Kneedragger, since your bike requires manual adjustment, you're valve train is either going to have a rockerarm type system with threaded screws and locknuts (easy) or use shims of various thicknesses to adjust the clearance (harder). Some have the shim on top of the 'bucket that covers the valve spring. With these, you will need a small, rather inexpensive tool specifically made for your model engine to compress the spring, allowing you to remove the shim. Other engines have the shim under the bucket, requiring you to remove the camshaft to change the shim. No special tools needed here, but reinstalling the camshafts correctly is absolutely vital. While this proceduere sounds rather intimidating, just remember that checking is all that may be necessary and no adjustments will need to be made. To check clearances, the idea is to turn the camshaft to that the cam lobe is pointing away from the valve and then measure the clearance with a feeler gauge and see how that compares to the recommended clearances. On shim type, clearances nearly always tighten and if the clearance is too little, you will need to install a thinner shim. I write down the clearance for each valve each time I check the clearances. If one valve tightens up faster than the others, this will give you a heads up to a possible future problem. Or, you may find they are ok this time but at the next check, you find some that need adjustment and will decide to take it to the shop that time. After a few checks and recording the clearances, you'll get a pretty good feel for how often you need to check them again. If you decide to do it yourself, by all means, get a shop manual.
Q:Can someone explain mitro valve prolapse vs mitro valve regeritation?
MItral vale prolapse is the problem that is causing the regurgitation. Regurgitation is backward flow of blood. Prolapse is a situation where an anatomical part has slipped out of its normal position. When a heart valve is prolapsed it doesn't close completely, and blood leaks backwards when the heart beats.
Good call, it most likely is the valve clearance. As the valves wear, they get tighter until they actually stay open a bit (when cold). As the engine warms up, the aluminum head pushes the cam away from the valve stems a bit, and some clearance comes back. Check 'em, adjust 'em, and you should be good to go. For most chinese 150's, you'll need to remove the plastic around the engine, then pull off the valve cover - you'll see the rocker arms inside, with locking nuts and adjustment screws. Set the crank at TDC on the compression stroke (about 1/2 turn after the intake valve closes) and then adjust the clearance - get specs from your manual, or just make sure that there's at least 0.1 mm gap if you don't have the specs.
Q:Valve cover oil leak?
Sounds like you should clean your engine, then take a look to see where the leak is. Have you tried tightening the valve cover bolts?.
