Chainsaw wont stay running

Sounds like a choke issue. but I am no expert on Bikes.

1. Make sure dead mans handle is fully depressed
2. Squeeze throttle in
3. Push choke switch all the way down
4. Pull saw over till it fires
5. Click choke switch up one position to half choke
6. Pull over saw until it fires up, saw should start running at high rev's
7 .'blip' throttle for saw to return to tick over.

If the choke switch doesn't stay down in section '3' check chokelinkage to carb.

more information please..

To lock the choke on:-
1. depress dead mans trigget on top of back handle
2. squeeze throttle trigger fully in.
3. slide on switch fully down to 'full choke' position. 'it should stay there'.
4. Pull saw over until it fires once.
5. click 'on' switch up one position to 'half choke'
6. pull saw over again, saw should start running and be revving high.
7. 'blip' throttle, saw should stop revving and run on tick over.

take off the muffler and try it if ok then open it up and clean the carbon from the screen

On the carburetor got two screws to adjust the carburetor. The first is to adjust the saw when working at high speeds. Another is when running at low revs. It is best to either put back for about 1.5 cycle of the maximum of the end of the rotation of the screws. If then the saw starts, then you can adjust it fine at higher revs (H), then at low (L). Have can be minimum screw that stops the chain.

The choke system is connected to the half throttle position, if you lift the throttle trigger the choke pull will automatically return, whilst trying to start do not lift the throttle trigger, the starting procedure is, pump the primer bulb as many times as it takes to 3/4 fill the bulb, pull the choke pull fully out, this will switch the saw on and engage the half throttle, crank the engine until it fires once, do not continue to pull,it will actually not run on full choke, if you do continue to crank with the choke fully out, you will very quickly flood the engine, now push the choke fully in, now crank the engine until it fires up, lift the throttle trigger once, this will dissengage the half throttle, and it should now come down to idle.

Check the fuel filter, air cleaner, and muffler for plugging. Check the fuel lines for decay or other problems. The idle speed screw (turned CCW) will slow the engine down. Hope this helps!

Sounds like the carb needs to be rebuilt. Those tiny jets will clog easily and need to be replaced. The diaphragm is also a large part of bogging and dieing. Hope this helps.

It has a crack in the fuel line between the body and the tank. The crack lets air in the line. Replace the line.

This does take a little time to get it just right. Start at one full turn for the h and l. Work on the high first and after you get the H running work on the Low. They have to work together. So if you get it to idle and run at full throttle but it hesitates when you pull the trigger just adjust the low a little higher.
