Why won't Yard Machine by MTD Model 2M1 snowblower shut off when key removed?
More than likely the wire that runs from the ignition switch to the kill switch is disconnected, loose, or broken. The wire starts at the OFF position of the ignition switch and connects to another wire that shuts off the engine.
What causes chainsaw chain to tighten during use?
I am a proffessional Timber faller in Idaho and use Stihlms440,ms460 and ms660 five days a week 7 hours a day in conventional logging operations. The answer to this question has to do with the bar and lubricating system. Most saws now days have an automatic oiler or pump that is enabled only while the saw is running... On your guide bar (if taken off) you will notice a small hole near the powerhead end of the bar. Usually the primary reason for the chain to tighten up is because the lubricating port on the bar ("small hole"as mentioned) is plugged with sadust,saw chips and small woody debris, thus not allowing the oil being pumped to pass through to the guide bar. First I would take a small nail or even a twig and push the debris through the hole. Depending on make and model of the saw and bar there may be two holes. If so clean them both. Now since you have the bar off and in hand you may as well clean between the bar guide rails. (Bar groove) This is most easily is done by using a knife blade. Start up by the bar tip (Sprocket) insert the knife blade into bar groove and carefully pull through the bar groove all the way to the opposite end of the bar. You may have to repeat this step two or three times to completelly break free all of the debris from within the bar groove. Do this carefully and with gloves. complete this on both sides of the bar. This will break loose and woody material that may have clogged the bar groove. Re-assemble the saw,adjust chain tensioner so your chain is at the propper tension and give it a whirl.
Can you jump a ski-doo mach 1 670?
You can jump any ski-doo, provided enough power and the right angles. But is it a good idea? Not unless you know what you're doing, so I do not recommend it, because you can get really hurt.

How do you make a balloon powered car?
Make up the car body and turn upside down. Cut the bendy
section off the straws. Tape the straws onto the base of the
body making sure they are parallel and about 2cm from the front
and back edges.
2. Push a white stick through each straw. Then push a wheel onto
each end of the sticks. The white sticks should be able to spin
freely with the wheels firmly attached.
3. Blow up the balloon a few times to stretch it. Fit the balloon over
the end of one of the straw off-cuts and secure in position with
tape. This is for blowing up the balloon when the car is finished.
4. Very carefully make a hole in the back of the car body using the
pencil. Push the straw that is fixed to the balloon through the
hole in the car body so that the balloon is inside the car body
and the straw is sticking out of the back. Use tape, plastercine
or blu-tac to fix the straw into position.
5. Blow up the balloon, pinch the straw to stop the air escaping
and place the balloon car on a smooth surface.
What is the gas oil mix for a 1985 ski doo citation?
Its Either 40:1 or 50:1 but you should consult your local Ski-Doo dealer just to be sure
What is the cop of vapour compression cycle?
3. Vapour Compression Refrigeration Cycle
Vapor-compression refrigeration is one of the many refrigeration cycles available for use. It has been and is the most widely used method for air-conditioning of large public buildings, offices, private residences, hotels, hospitals, theaters, restaurants and automobiles. It is also used in domestic and commercial refrigerators, large-scale warehouses for chilled or frozen storage of foods and meats, refrigerated trucks and railroad cars, and a host of other commercial and industrial services. Oil refineries, petrochemical and chemical processing plants, and natural gas processing plants are among the many types of industrial plants that often utilize large vapor-compression refrigeration systems. Refrigeration may be defined as lowering the temperature of an enclosed space by removing heat from that space and transferring it elsewhere. A device that performs this function may also be called a heat pump.
The vapor-compression uses a circulating liquid refrigerant as the medium which absorbs and removes heat from the space to be cooled and subsequently rejects that heat elsewhere. Figure 1 depicts a typical, single-stage vapor-compression system. All such systems have four components: a compressor, a condenser, a Thermal expansion valve (also called a throttle valve), and an evaporator. Circulating refrigerant enters the compressor in the thermodynamic state known as a saturated vapor and is compressed to a higher pressure, resulting in a higher temperature as well. The hot, compressed vapor is then in the thermodynamic state known as a superheated vapor and it is at a temperature and pressure at which it can be condensed with typically available cooling water or cooling air. That hot vapor is routed through a condenser where it is cooled and condensed into a liquid by flowing through a coil or tubes with cool water or cool air flowing across the coil or tubes. This is where the circulating refrigerant rejects heat from the system and the rejected heat is carried away by either the water or the air (whichever may be the case).
The condensed liquid refrigerant, in the thermodynamic state known as a saturated liquid, is next routed through an expansion valve where it undergoes an abrupt reduction in pressure. That pressure reduction results in the adiabatic flash evaporation of a part of the liquid refrigerant. The auto-refrigeration effect of the adiabatic flash evaporation lowers the temperature of the liquid and vapor refrigerant mixture to where it is colder than the temperature of the enclosed space to be refrigerated.
The cold mixture is then routed through the coil or tubes in the evaporator. A fan circulates the warm air in the enclosed space across the coil or tubes carrying the cold refrigerant liquid and vapor mixture. That warm air evaporates the liquid part of the cold refrigerant mixture. At the same time, the circulating air is cooled and thus lowers the temperature of the enclosed space to the desired temperature. The evaporator is where the circulating refrigerant absorbs and removes heat which is subsequently rejected in the condenser and transferred elsewhere by the water or air used in the condenser.
To complete the refrigeration cycle, the refrigerant vapor from the evaporator is again a saturated vapor and is routed back into the compressor.
Refrigeration Process
Process Description
1-2s: A reversible, adiabatic (isentropic) compression of the refrigerant.
The saturated vapour at state 1 is superheated to state 2.
⇒ wc = h2s− h1
2s-3: An internally, reversible, constant pressure heat rejection
in which the working substance is desuperheated and then condensed
to a saturated liquid at 3. During his process, the working substance
rejects most of its energy to the condenser cooling water.
⇒ qH = h2s− h3
3-4 An irreversible throttling process in which the temperature and
pressure decrease at constant enthalpy.
⇒ h3 = h4
4-1 An internally, reversible, constant pressure heat interaction
in which the working fluid is evaporated to a saturated vapour
at state point 1. The latent enthalpy necessary for evaporation
is supplied by the refrigerated space surrounding the evaporator.
The amount of heat transferred to the working fluid in the evaporator
is called the refrigeration load.
⇒ qL = h1− h4
How do barnacles damage boats?
- Barnacles stick to the boat hull and grow creating a sort of skin over the hull. This in turn slows boat by taking away smoothness of hull and adding weight. Barnacles get knocked off and fall off , which pulls outer hull coating off allowing rot to get in.

How do you clean air filter Yamaha yfm200?
To clean the air filter on a Yamaha YFM200 remove the filter. Spray the filter with filter cleaner that you can by at a home improvement store. Fill a bucket with warm water and dish soap, swish the filter in the water and soap. Rinse the filter in a bucket of plain water. Only wash foam, or cotton filters, not paper.
Can small engine primer bulb be bypassed?
Primer bulbs on small engines take the place of a choke on the carb . If your carb has a choke on it then you could probably bypass it . The object of the primer and the choke is to give the engine a extra charge of gas to help it start when the engine is cold . If you take this away then the engine will be hard starting if it starts at all .
What is the valve clearance of a Honda GX35 engine?

Ski-Doo SDI - a quite different and more economical route to low two-stroke emissions and fuel consumption. SDI stands for Semi-Direct Injection, and it describes a system by which fuel is injected, not into the combustion chamber, but into the fast-moving air streams in the rear transfer ports. Because injection into the transfer streams more than doubles the amount of time available for evaporation of the fuel droplets, specialized fuel injectors like those of Orbital and Ficht are not needed. Direct Injection must wait for the exhaust port to close before injection can begin, but with SDI, keeping fuel from reaching the exhaust is accomplished by the natural scavenging flow pattern of a high-powered two-stroke.

How many horsepower in 370 cc?
There is no set amount of horse powers per cc, it depends entirely on how efficient the engine design is, the type of fuel and other factors, this is easily demonstrated by a 4 stroke lawnmower engine, of 160cc (I used a honda gx160 for this example), which produces 5.5 hp and a 2 stroke 125cc (FR125 Rotax Max in this example) engine which produces 22hp.
As I said, its all in the design.
Sorry I couldn't answer your question.
Hope this helps.
