Stihl 015av won’t start and floods

[Tomas Caballero]

I have reassembled the Stihl 015AV after ultrasonic carb clean, new carb kit and new metering lever. I adjusted the metering lever per manual even with the carb walls. Fresh new fuel mix. I tried to start it on choke. It gave me a bit of a grumble like it wanted to start after one pull. I took choke off and pulled 3-4 times. Fuel started to come out of the throat of the carb. It was flooded. I set it aside and a couple of hours and it had leaked half the tank on the bench. Thankfully I had placed it on paper towels.

Here’s what I’ve done so far.
Carb clean
Carb kit plus new metering lever
New spark plug NGK BPMR7A as this is listed as a replacement for the Champion CRJ6Y.
Strong spark
Compression after three pulls is 118 PSI.

Any ideas? I’m chasing down the fuel leak. Hopefully the hose. If it’s the hose I plan on getting the one that fits regular filters as the square felt filter seems a bit tired although I did clean it up and dry it and fuel obviously is getting through. If not an IPL shows a gasket between the integrated tank and the fuel/oil plugs.

I am also posting in the beg for manuals thread for a service manual. Thx! Tom

Took the shroud off. I hand turned the flywheel and fuel started dropping from the bottom right corner of the end cover (where metering assembly located). Maybe the gasket for the metering diaphragm from the kit is defective or? No clue. I would like to fix this saw but I don’t want to throw more money at it. Thx. Tom

EDIT: sorry for the crappy nomenclature/terms. I'm a newbie. I retightened the screws on the end cover and the leaking of fuel stopped. Got the saw running for a little bit but couldn't restart it and it flooded again.

Not sure what you mean there.
What do you mean by carb cover?

 

[Wood Doctor]

Just in case, but the 015AV might be a different saw. I also have the IPL. Holler if you need that too. 118 psi compression is a bit low.

He might mean filter cover.

That would be ... the shroud so I could access the carburetor. Sorry.

Sorry. I meant the shroud to access the carb. and thanks for the service manual!!!

By retightening the screws on the metering end cover the leak stopped. Got saw running but wouldn't idle. It shut off. Could not get it restarted and after four pulls it flooded. It's a cool little saw. I like how it is one of the lesser quality saws for the day. And yet it still fits together like a clam.

As I recall, getting to that carb is not all that easy...

 

[HarleyT]

Did you replace the needle when you rebuilt the carb?

It puzzled me for a bit. You have to take out rear handle bolt that threads into the AV rubber pad (made up terms here).

New needle. I also had to replace a broken metering lever. I set it at same height as carburetor wall. Could that be it? Too high or too low?

 

[HarleyT]

Sounds too high. put up a pic.

 

[Tomas Caballero]

Cool. Thanks man. I will put up a pic when I come back home from work.

 

[Tomas Caballero]

Here’s the pic of metering lever setting.

And three pics where it is dripping fuel from. It’s a clean saw. Thx for looking and helping. Tom

 

[HarleyT]

No, read the service manual. Your needle looks like it cannot possibly close.

 

[HarleyT]

Post a pic of the metering lever without the tool.

Post a pic of the metering lever without the tool.

So it needs to go down? Up? Thx. Tom

How did you "remove" the old metering lever? And why?

 

[HarleyT]

It kind of "stays" with the metering plate.
