Q: I have a no start on a briggs and straon 16.5 OHV. It has spark, and fuel. and backfire's through the intake. I took off the top of the motor to check the key way and it was in place. I think its a valve timing issue but what times the valve? I have not removed the flywheel yet because i need a puller. Is there another key way under the flywheel that times the valves: you can,t tell if the key way is sheared by looking at the flywheel it has to be pulled, did you hit something when mowing? good indication that the key is sheared, the valves run off a cam like in a car if not then you have a burnt valve

Q: The hot water shutoff valve to the washing machine was dripping. I removed the packing nut and put in new packing over the weekend. Problem is that the packing nut seems to only go back on at an angle no matter what I do...it may have already been that way though. The valve isn't currently dripping, but I'm not liking the way the packing nut only goes on at an angle. Would it be crazy to keep the existing valve if I keep an eye on it and over time it doesn't drip, or is it too risky to keep this valve given that the packing nut is on at a funny angle? (Local plumbers here in Northern NJ all want around $350 if I were to replace both the hot and cold with a watts single handle valve.) Thanks, J.: I would do a little more trying to get the nut on straight. Turn it counter-clockwise until it drops a little bit. Then turn it clockwise. Question to ask yourself is, how long will it take you to get to the main house shutoff valve if the nut lets go? You should be able to replace just the one faucet for less than $10.

Q: I went to turn the water off with the shut-off valve so that I could do some work on the toilet tank (replacing old and leaky fill valve) but the water won't shut off. I'm assuming that I'll need to replace the shut-off valve itself but could anything else be causing the problem? The funny thing is, the leaky fill valve that I wanted to replace has now stopped hissing and leaking and the tank seemingly fills fine. But of course the water can't be turned off completely.Just wanted to check make sure that there aren't anything else I should do or consider before I went off to replace the shut-off valve.Thanks: the shut off valves are soldiered on or threaded on it depends on which 1 you got. it might be easier to get a valve that looks like yours and putting the guts out of the new 1 into the old 1. as long as you can shut the water off to the valve

Q: I have been diagnosed with a bicuspid aortic valve and a discrete stenosis under the valve at 11 years old. I am now 25. My cardiologist told me I might need a valve replacement a 70. Can people actually live long with that condition? I don't understand it. And he only wants me to have an ultrasound every 3 years because nothing has changed in the past 10 years. Can my condition change in a short time? At a dangerous level? I have bad anxiety because of this.: The mitral valve between the left atrium and left ventricle only has two cusps and it works fine. Since the valve going into the left ventricle has two valves, it stands to reason that a similar valve going out of the left ventricle would function similarly if it was the same size and shape. The number of cusps is not entirely related to how well the valve functions. In your case, the opening of the aortic valve is slightly smaller than normal, but clearly capable of passing an adequate amount of blood. The stenosis alone may be the only problem caused by the valve. The stenosis you have likely creates some back pressure when the left ventricle contracts. The heart compensates partly for the back pressure but this prolonged compensation wears on the heart valve a little more than normal. So, you end up with a heart that more or less functions normally but the back pressure and compensation cause the heart valve to wear out faster than normal. Its a gradual effect. The type of damage done from this circumstance is not something that changes rapidly. Evaluating the condition every three years is still probably a very cautious approach and its not certain that the stenosis will ever become a significant problem even if you live well beyond 70 years.

Q: 1991 Buick Spirit smokes early for five minutes in morning, from exhaust. Tried every carburator and gas cleanative fluid. Mechanic says Valve job'.: Probably just the valve stem seals need replacing. NOT a entire 'valve job'. The seals help scrape oil off of valve stem to lower the amount of oil weeping into cylinder when engine is running or turned off. As the rubber ages, it cracks and loses its elasticity and doesn't wipe the stem properly. This is a lot cheaper versus a full 3-angle valve job which requires removal of the heads.. Get a second opinion.

Q: 1. Why is there an exaust valve. Isnt it only a port. Where do the gases that go into the exaust valve go?2. How does air enter the intake valve. If you look at a push rod diagram, you cant see where the air is enteringCan someone explain to me the valve concept: Hey mechanic wannabe, The intake valve opens, the piston moving downward pulls the fuel mixture into the combustion chamber, the fuel explodes under pressure caused by the piston rising and both valves remain closed. When the piston comes back up the exhaust valve opens and all the burnt fuel leaves the combustion chamber and goes down the exhaust pipes until blown out the end of the exhaust system.

Q: where is the fuel tank selector valve located on the truck?: Located under the LH center of vehicle, on LH frame rail

Q: This valve has flow indication embossed on their body.: Gate valves are used primarily for isolation, usually not for flow modulation. They are usually operated fully open or fully closed. Installing the valve with the arrow pointing in the direction of flow will have more to do with the tight sealing of the closed valve than with the operation when open. If the valve is to be installed in a pipeline where the flow is in either direction, pick the direction most important for good sealing. However, I do not recall seeing a flow arrow on a conventional gate valve.

Q: ex: 4 stroke 16 valve engine: ? r u going to include the number of cylinders?

Q: Does anyone know what those valves are/do in my picture?http://img223.imageshack.us/my.php?image=dsc00531it9.jpg: I'm a licensed Plumber and this is what those are for....if you doubt me contact Delta and speak with their customer service reps... Those are Isolation valves that plumbers use to turn off the water to you shower to make repairs within the shower valve its self (O rings...mixing cartridge, etc).....otherwise the water would have to be shut off to the whole house when making a repair. That and if you look closely they are NOT part of the valve its self....the look like valves that are attached (Threaded) to the Hot Cold inlets on the valve. My first guess...that is a Delta, Monitor, Shower Valve. Maybe a Moen positemp...but I'm pretty sure its a Monitor Series Delta valve. They're are BOTH very similar.
