55cc air induction chain saw wont start,keeps flooding

There are several conditions and situations that this can occur, but let's try the most common. This is also for any STIHL saw that was manufactured before 2014, after that, the M-Tronic saws have a different starting method.
Normally this happens when the engine fired and it was not audible, and the rope has continued to be pulled with the choke on.
This method is approved, but EXTREME caution should be used, and the CHAIN BRAKE must be used.
CAUTION: Do NOT use the drop start method, this is not an approved starting method under any circumstance!
1) Place the saw on the ground that is clear of debris.
2) Set the Chain Brake
b) place the toe of your right shoe thru the rear handle,
c) support the saw top handle with your left hand,
d) pull the recoil with your right hand.
3) Make sure the choke is NOT applied, place the master control lever in the start position (one notch above the choke position)
NOTE: at this point, it helps if a second person can hold the throttle at the full or wide open position.
4) Make 6 rapid pulls (a few more may be required), you should hear the saw start to sputter, keep the throttle open until enough rpm is obtained that YOU the Operator can gain control of the throttle (the other person stands aside now in a safe position) and remove the chain brake. Keep the throttle open until the saw starts to run properly.
*NOTE 2: The chain brake is designed to not only stop the chain in case of 'kick back', but also is to be used in starting the saw until you have time to gain full operational control of the saw. However, extended rpms above clutch engagement can damage the brake band, overheat the drum bearing, damage the clutch shoes and clutch drum.

Do a complete tune up.
1-spark plug
2-carb filter
3-coil induction

And if possible try to open the piston cylinder head and clean the piston head and the head for carbon deposit.

If you need more help post back!
Thumbs and testimonial are welcome!

I would say there is inadiquate oil to the chain, make sure you are using proper chain oil, remove the bar and clean out the oil holes, check there is a good spray of oil from the end of the bar.

Chain saws are 40-1
3.2 ounces 2-cycle oil per gallon of gasoline

Flooding is caused by a plugged air cleaner, or lack of control by the diaphragm in the lower chamber of the carburetor. Usually, the diaphragm becomes hard or cracks and is unable to regulate the fuel volume in the lower chamber. There is also a needle valve in the lower chamber which the diaphragm controls that can become defective. Go to: http://www.drystacked.com for a 12 page article on Walbro brand carburetor theory and troubleshooting. This applies fairly well to other carburetor brands as well. Hope this helps!

I didn't know that chain saws had fuses? The black handle you are talking about is a chain break, push it forward allows the chain to drive, if chain break is back chain will not run around the bar, safety for saw kick backs.
If it will not start:
Check and see if it has fuel.
Is the switch in the on Position?
Do you have a fowl plug? is there spark?
Is the plug wire attached correctly?
Do you have fuel going to the carb?
Is your air cleaner, clean?
DO you smell gas, if so you have probably flooded it and now you will have to remove the spark plug and get rid of excess fuel or try starting the saw with the choke on.

25 to 1

Fuel oil mixture is deturmined by the brand of mixed fuel you use, not the machine. The machine will state what it's recommended oil brand states. Example a stihl chain saw will be 50:1 with stihl oil but if using echo oil it would be 35:1.

the fuel lines were hooked up backwards thanks

If checking spark make shore the out side if plug is earthed to chain saw.
Fresh clean fuel, clean fuel filter filter pull exhaust off and check piston is ok. Than check for flooding. start there.
