Instructions

    • 1 Locate the red button on the top of the handlebars. This is called the "kill switch." When you pull it up the engine can run; when you push it down, the engine will shut off immediately.
    • 2 Pull the kill switch up.
    • 3 Turn the key to the "on" position.
    • 4 Make certain the cord running from the key is attached to the steering column. This device acts in the same manner as the kill switch - the engine will run only when it is secured.
    • 5 Pull the start cord, which looks like an enlarged lawnmower pull-cord and is generally found on the right side of the machine.
    • 6 Listen to the engine - if it starts, let it get going slowly . If it "pops" but does not continue to run, try pulling the start cord a few more times. If you do not hear the engine turn over at all, proceed to the next step.
    • 7 Find the pull tab under the right side of the handlebars. This is called the choke - it often has a circle with a diagonal line through it. The choke helps to start an engine when the weather is very cold or the machine hasn't been used in a while. When using the choke, try leaving it on only long enough to hear the engine fire a couple times, then return it to the "off" position. A choke left on too long can flood the engine.
    • 8 Place the choke in the vertical position - this is called the half choke position. Pull the start cord several times. If the engine fires up, place the choke back down to its original position and let it slowly warm up. If the engine still has trouble starting, proceed to the next step.
    • 9 Pull the choke 180 degrees from its original position - this is called the full choke. Pull the start cord until the engine sputters a couple times.
    • 10 Replace the choke to the original off position and continue to pull the cord. The engine should fire up and settle into a steady hum, ready for fun in the snow.

84 ford f150 carburetor was rebuilt runs great when cold kicks and bucks when warm have to stomp on throttle to get to go


Sounds as if your choke is hanging up, or not opening at all. With the engine warm remove the air cleaner, there is a butterfly valve right inside the top of the carburetor If this is closed or mostly closed your choke needs to be adjusted. There are manual and electric chokes, yours should be an electric choke. First with engine cold and the key turned to on check for voltage at the choke wires. If you have voltage, then you might just need to adjust your choke. Electric chokes heat up an element inside the choke to tighten a spring and open the choke butterfly valve at the top of the carburetor. There should be between 4 and 5 screws that hold a ring around the choke housing on the side of the carburetor with the wires going to it. While holding the round choke housing in place loosen all of the screws on the retaining ring. If you can feel the choke housing wanting to spin turn it the opposite way that it wants to turn. Do this in stages until your choke butterfly valve is open with the key turned on, or the engine warm. Hope this helps if you have more questions just ask.

I have a sym 100 Euro jet that will not start in the cold


if real cold wheather the oil is thick and will make starting sluggish, or not at all.
it takes alot of cold cranking amps to start a cold motor. you could probably jump start it with a battery charger that has 50 amp start option.

if you think its carburation.........your automatic/manual choke may not be working, check cable adjustment, and lubricate your cables.
you can pull the choke out and clean it.

Once the machine has started the valve will automaticallyreturn to its original setting.Air purge: Press the air purge diaphragm repeatedly until fuel fills thediaphragm (at least 6 times). The diaphragm need not be completely filled.Grip the front handle with yourleft hand. Hold the chain saw on the ground by placing your right foot throughthe rear handle.Pull the starter handle, 4: Pull the starter handle with your right hand and pull out thestarter cord slowly until you feel a resistance (as the starter pawls engage)then pull firmly and rapidly until the engine fires.Push down the red choke control: As soon as the engine fires which can be heard through a"puff" sound, push down on the red choke control.Pull the starter handle (6): Keep on pulling the cord powerfully until the engine starts.
