Small Engines

no

THIS MAY BE LATE FOR SOME, BUT HELPFUL FOR OTHERS. I had a stalling issue with my 2001 700 formula, had new teather programed,but it didnt fix problem. After reading tons of posts .I found one about the plugs, If your sled calls for B9res plugs make sure you dont install b9es plugs, as i did, the lack of the resistor plug will cause stalling. Hope this helps someone....

about 18 to 22 hp

engine has bad intake valve,

Try cleaning the muffler cleaning the carburetor and decarbonizing the engine by disconnecting the PCV hose and running the engine untill it warms up. Run the engine at wide open throttle and trickle two gallons of water down with the air filter off. What this does is builds up a LOT of steam and blows carbon out like magic. Hope this helps!

hey,

The more balloons you have, the more the force will be to move forward. So yes. btw there are a lot of balloon car websites. I have just recently made a balloon car myself and won farthest distance.

That size sled runs about 65 to 75 mph.

There are a few things that cause this. Not being sure of how long it takes before the engine overheats I will give you a few common causes. Thermostat not working properly (Mounted on top of engine where cooling hose hooks up) . Can be tested on a stove, need a pan, some water, a string, thermometer able to read over or at least 250 degrees. Open the thermostat insert an end of the string. Tie the other end of the string to the handle of the pan, as to keep the thermostat about half way up the side of the pan. Fill pan with water just pass the thermostat, and place on the stove. Bring water to a boil, before the water boils the thermostat should open and fall to the bottom of the pan, you should be checking the temp of the water with the thermometer, so you know the water temp when this happens, it should match, or be very close to the temp stamped on top of the thermostat. If water boils and thermostat does not open, get a new one. Another common cause is air in the system, there may be points in the system higher than the fill point, with today's rear suspension system this has become an issue. To fill this type sled with coolant you must raise the fill point. This can be done with a jack. or even a snowmobile trailer. With a tilt bed type, load sled, tie it down, brace the bed up, this will raise the fill point. With a ramp type, just run the sled up on the ramp. When using a trailer always have it hook up to a auto. A steep ditch , or hill will also work. Good luckCheck you **************check your water pump belt for wear/brakeage it is located behind the rewind assy, and make sure you are driving in powdered snow as driving on ice does not cool the engine because snow passes over the heat exchangers and cools the motor*************

Tecumseh made an engine called the Snow King, which was used on many snow-blowers made by different manufacturers. I do also remember a blower under the name Snow King that was made by a long gone manufacture.

The lowest ring is the oil ring

Under the rear of the tunnel there will be studs with nuts on them. Remove the nuts, lift the seat until the studs clear the tunnel frame. Pull the seat back to release the front retainer, now you can lift the seat, and unplug the wiring, and remove the seat.

Looks to be 40:1 gas to oil

1. If you mix the fuel with too much oil you will foul the plug.

2. If you put too little oil in the odds are good you will seize the motor.
