Okay when I have the chain and bar off it fires right up and runs. When i put the bar on it won't start or if it does it has problems running. If I get it started and start to cut it will get maybe half way through the log and stall out. If it starts to stall out and I pull it back out of the log it will run fine. If i have it half way through the log i can only run at half throttle. If i give it full throttle it will stall out. What in the world is wrong here?  ?? |

Not getting gas..... When it's under a load it sounds like it is starving for fuel!!!

You may also have the chain too tight.

Would a bent bar cause this. It looks bent but if it is its very very slightly. The chain isn't too tight. I thought that and loosened it up quite a bit. If it wasn't getting enough fuel wouldn't it stop it running when the bar and chain is off. It seems to run fine with the bar and chain off. Also when I do get it to run and its cutting fine when I cut through whatever and I let off the trigger it dies every time. New chainsaw time???

I can't pinpoint the problem but I seriously doubt that it's time for a new saw. What saw is it?
Things to check for:
Dirty orafice on the bottom of the carb. Dirty air filter. If the chain isn't too tight, does the sprocket on the nose turn freely? (if it's a sprocket nose) When you have the bar and chain off, did you clean the bar before re-installing? Does the chain turn pretty easily if the brake is off and the saw not running? Are/did you use gasoline with ethanol in it? If so, did you use marine grade stabil?
Have you tried running a tank of fuel thru it with seafoam in the fuel too?

try pulling your fuel hose out of your tang and check to see if it is collapsed damaged with cracks or splits

I would check the bar and make sure the sprocket turns freely and the teeth aren't too worn.

I wonder if that is partially clogged? I carry a 1" wide paintbrush in my chainsaw "kit". I always brush off all the dust and junk that collects around the fuel and bar oil caps before I open them. |

What pitch is your chain? Is it the same pitch as your sprocket on the saw and bar. Is the gauge size the same for bar and chain? In other words your not running .063 gauge chain on a .050 bar are you? It sounds to me like you have a bar chain problem,or as someone else said a badly worn sprocket. What brand and model saw do you have?

Greetings
It is carb out of tune, could be a number of reasons
1 carb vibrated slack, check mounting screws.
2 dirt in the carb.
3 needs a carb kit needle valve and diaphragms
If you have never done one it is difficult to explain.
Check mounting screws,if ok fire it up and open the jet marked h very slightly if no improvement put the jet back to its original setting, then do same with the L jet.
If No improvement it's inside carb, probably dirt by sounds of it.
What saw is it, and how much work has it done?
Regards
Billy

I'd replace the bar (if bent), buy a new chain; if nothing else isn't wrong with the saw. ALSO, use 89 octane fuel that has no ethanol with proper oil 2-cycle mixture. I was told, by a local dealer, that ethanol is very hard on small engines, and we have a few gas stations down here that sell non-ethanol 89 Oct. gasoline for boaters and lawncare businesses. |

Take it to your local saw repair shop! It could be as simple as replacing an ignition module, a fuel filter, &/or the carb.

Lowes will not give you full service like a good dealer can. If you do have problems with a new saw Lowes will have to send it off for repair and a dealer can get you back to cutting wood in a day usually |

As for buying a new chainsaw; I bought one from a local Hardware store, and I suggest buying a Stihl. I bought a couple of their model MS-192 14", which has not given me any problems. |
