Unhappy Chain saw starts, stalls and leaks gas

My abused 35+ year old Homelite Super 2 14" chain saw stalls after running a few seconds. Some gas then leaks out of the housing. The saw now refuses to start after stalling. This behavior started after successfully cutting a few tree limbs. Any suggestions on the cause of the problem?

I would start by inspecting, and likely replacing fuel lines.

Thanks BFH. I'll take a closer look.

The one fuel line is pliable (no cracking or rot). The filter inside the tank is clean. I am thinking carburator?

Also check the muffler to see if it's carboned up inside to the point that the exhaust gases can't get out.

Thanks for the response, Joe. Already checked the screen. Some carbon, but certainly not clogged.

Chances are you will wind up with the carb off, so may as well get it over with IMO. Get the make and numbers (we can help with that) and make sure a kit is available.
Open it up check it out...stiff rubber no doubt and who knows what else ya may find.

The carb is a Walbro. The only number that I see is 4 21-416. Haven't been able to find a kit under that number.

Here you can see where to find the numbers and some clue of what they mean.


Manuals once you find your series.

Thanks again BHF. Found the carb ID and the manual. The manual gives good info; however, can you advise me where to find rebuild guides or tutorials? This is my first rebuild.

Lot of folks seem to be finding a need to make you-tube videos of this type of stuff, However, many I have seen are not completely accurate or seemingly knowledgeable.
Not too much to it really, take some photos if you can before you start. Note all connections whether it be hoses, wires, or linkage. Disassemble noting how the gaskets stack and where the parts are. Count the turns on the needles and then remove them also. Get some canned carb and choke spray from auto store or walmart, spray through all passages and blow with compressed air and reassemble.

Have been researching the rebuild info. I'll order a carb kit and give it a try. I'll let you know how things turn out when it is done.

BFH and Joe, I found the fuel pump cover screw loose when inspecting the carb. Put the saw back together and it now runs just fine. It all makes sense (stalling and fuel running out). I will still get a carb kit since the saw is so old. Now that you have enlightened me on carb basics, I intend to rebuild the carb on a Poulan Pro 422 leaf blower that will not run. I suspect a gummed-up carb. Thanks so much for your help. You saved me $200 for a new saw. Who said Homelite saws were junk?
