I have a csp 4518 after starting my saw and pushing trigger it dies out can you help me please

What type of saw is it? Did it work before? Mine is a 'Parside' and it does not start immediately when pressing the trigger. You have to hold it in. It starts slowly and quickly pick up speed.

After some use sawdust can cover over the rotating magnet in wheel which passes coil to create spark.remove cover and clean or can try blowing out with compressed air without removing cover.,other problems can also cause no spark.the gap between wheel may have shifted and is touching.had a saw which a elbow which has wire to ground head had weakened and snapped so head wasn't grounded.try first solution which is common then try others.

To change that trigger switch on a Remington saw, you need to open up the two handle halves and expose the switch. The wires are just "poked" into the switch, so you can make a tool to release them. I used a 1/16" diameter short length of wire and flattened about a 1/2" of it on an anvil. Push it in next to the wire and the wire will pull out, wiggle the tool a bit and it will pull out too. Push the wires into the new switch and put it all back together.

The switch is probably a #077525S ...seen them out there for $8 to $15.

The most probable cause is the oil line inside the saw from the oil tank to the pump or oil flow being blocked at the rubber ball that you can see when you remove the chain, bar and plate before it has a chance to get to the bar. in my case i had the oil line itself blocked from dust getting into the oil tank over time

Run too lean, this is fuel starvation, remove the fuel line from the tank and replace the filter on the end, check the fuel hose from the tank up to the carb for leaking or cracking.

Did you read the starting procedure in your OM? It is similar to this:
Start Procedure
Cold:

1. Ignition on/off to on.
2. Set compression release – optional step even if saw is equipped with a compression release.
3. Pull (close) choke, set fast idle (done when choke closed on some saws); pull starter and listen for an attempt to start. once heard (usually two pulls; no more than 4).
4. Set compression release – optional step even if saw is equipped with a compression release.
5. Push (open) choke pull starter until it starts. (usually first pull).

Warm:

1. Ignition on/off to on.
2. Set compression release – optional step even if saw is equipped with a compression release.
3. Pull (close) choke, set fast idle (done when choke closed on some saws) – Do not pull with choke closed.
4. Push (open) choke, pull starter until it starts. (usually first pull).

Flooding is most common reason for hard starting in 2-cycle engines.

After never using for 6 months, I finall had the need to use my Ryobi saw and had the same problem. Push the switch and it would make one revolution and die. I took the blade off and the end cover oppsote end to epose the other end of the motor shaft. Applied small drop of oil to each. Continued to play with trigger and finally got the motor to get running. Held it on for several minutes. I had to do this several times in order for it to start working properly. Might ne something with breaking in the brushes. Regadless, it works now. Give it a try. Be patient.

Let it warm up first ...

• plugged fuel filter
• cracked/loose fuel line allowing air (instead of fuel) into the carburetor.
• poorly fitting fuel cap
• plugged or disconnected/broken pumper line
