Scratching my head...

Mine go like hell with a dull chain. Just don't get anywhere.

Have you tried undercutting? It seems if downward pressure is causing the symptom, could it be possible that wherever the air leak is, it s made worse by downward pressure?

That's what I was thinking...

Dull chain makes saw bog?

It was the problem here.
Edit: or possibly a half dull half sharp?

Sounded like it had other issues. So with a sharp chain that saw is ok now?

I'm with you Dan, sounds like that 621 has other issues besides a chain that is suspect.

I thought it had carb issues and switched carbs and inspected fuel lines etc with no different results.
After ruling all that out I put the chain on the grinder and filed the rakers. Went back to wood pile and it did great. It didnt make sense because I have had uneven chains cut to one side or other. But this one cuts great now and i gave it to my brother for Christmas and he has ran several tanks threw it with no issues.
Btw i made the video to post here for advice but got it going so never uploaded to youtube until today.

Sounds to me like it needs 1/4 turn out on the h jet. It's lean

sounds like you people need to buy a echo and forget about you're problems.

If you were new here I'd say no way. But I know you know your way around a saw. I've never had a chain slow a saw like that unless it was binding from cutting crooked. Usually saw just screams and doesn't cut anything. Lol.
I'm sure I'm missing something. Hence the had to be there...

I am still just a hack. You guys are the real experts. Next time i am at my brothers i will fire up the saw again and see if the problem came back. I guess binding would be the only answer chain related and the video was shot before i had touched the chain or bar. Btw sorry to OP for derail of thread.

I would definitely be interested in hearing it run again.

Uneven guides will cause binding also, very well could have been your issue.

Is this about the 240 from the 1970s (a small pro saw with a metal case), or is it about the more current Poulan made POS one?

Good point ! I assumed the newer one .

Yes, I could see that - and that's what triggered my question.

The model numbers 40, 240 and 340 all have been used two times, on very different saws.
