Chainsaw won't start

[dogdayz]

I'll have to pull the carb and disassemble it for a good cleaning in the next day or two. If that doesn't work then I saw a good price on ebay for a new complete carb that comes with air and fuel filters, fuel lines, primer, plug and gaskets.

check the vent hole in the gas cap, it may be plugged

Did that before, thanks.

I took the carb apart as much as I could this morning, sprayed it good with cleaner - let it soak. Took out the needles and readjusted.
Didn't help!
Guess I'll order a new carb, if that doesn't work then I will have a Jonsered boat anchor.

The chainsaw should fire even if a carburetor isn't mounted with a little gas mix or ether poured in cylinder.You said it doesn't fire if so it has some other problem.

See post #12 - It does fire up, just can't keep it running.

If the carb is still on try turning both air and fuel adjustment screws clockwise until they lightly seat then turn them out 2 full turns.Adjust the L side until it idles probably turning L clockwise a little.If it idles try throttling up and adjust H side probably turning clockwise a little until it revs smooth and stays running.If it stays running do not turn H to max rpms because it will run engine to lean on fuel back it off a little..

I can give your suggestion a try. I did remove the screws when I cleaned the carb. I set them at one turn out. I'll try the two full turns. It's difficult to adjust when I have the saw put back together because I don't have the special knurled tool that is needed. I want to cut slots in the screws so I can use a flat screwdriver.

Try an electrical Butt Connector on the knurled screws. If you find one that fits snugly, you can turn with a small screwdriver or needle-nose pliers. It worked for me.

I have a set of carb adjustment screwdrivers now.But I have used a dremel with a cutting disc and cut slots in adjusters many times.

I just use a piece of heat shrink tubing, and let it stick out beyond the casing, once adjusted you can leave it or cut it closer.

Good idea but the screws are too stiff to turn with heat shrink tubing. I'll try and cut slots in them.

I have to wait until the weather cools off - just too dang hot to work on this outside.

Just thought I would update this thread in case anybody is interested...

I ordered a new carb from ebay and received it today. I put in the new carb and the saw started in two pulls - music to my ears!

So, I don't know what the issue was but now I am ready to cut wood again.

Thanks to all you guys for trying to help out.

old cheap gas... does it every time if it sits to long!
Glad you got it running!

FYI I work in a small engine shop and we don't rebuild carbs if that is the issue. Parts verses labour, new carb wins most of the time because of shop rate. Most of the time when we clean the carb in the ultrasonic cleaner you have to get it perfect and that rarely happens. So it's a new carb and 15 minutes later it's ready to go back to the customer.
