Small XL blowing fuel mix out of muffler (FIXED IT

[oleglass]

I recently posted a request for a gas/oil mix for this saw.
Thanks for the replies, I got some of the synthetic mix and some fresh gas, tried the saw and it cranked right up.
I had put a kit in the carb, before I tried to start the saw.
Also replaced all the fuel and oil lines and got a new fuel filter.

Shut it off to reread the instructions for setting the carb, and now when I try to crank it all I get is fuel coming out of the muffler.

It has not fired up at all since the first time I cranked the saw.

The plug is firing, and I even tried a new plug, still no run.

Any ideas as to the problem??

ETA:
I removed the carb and readjusted the needle valve control arm, cleaned the spark arrestor in the muffler, reassembled the saw and it ran great!!!

Thanks to all who gave solutions to my problems....

I would say check the inlet lever height or it's an issue with the inlet needle/ seat.

How are you testing the spark? I assume you are grounding the plug and then pulling the rope. This is OK but you should not have to pull the rope hard and fast. A gentle pull should get a spark. Dry the plug and check for spark.
How is the compression? These saws have a small rewind pulley so you should feel a pretty good pulse.

Carburetor next, here is a picture:



Item 8 is the screen, you didn't forget it did you? If something is holding the needle open you will have gas.
Make sure all the diaphragms and gaskets are installed in the correct sequence.
Check the spring that controls the lever. DO NOT STRETCH IT.
Make sure it is in its hole and under the dimple on the lever. I think on the HDC the lever is flush with the body casing surface. When the carburetor is together you can test the needle operation using a short piece of fuel line and a little puffing. Hook the hose to the inlet and gently blow into the hose. Use a pencil and operate the metering diaphragm through the hole in the bottom plate. You should be able to tell if the needle valve is working.
