Yes HDA 164 is the right carb.  Look in Carb fixes & mods there is a fix for the HDA 164 which should be on your saw.

The fix involves a new high speed check valve.  Don't know if we ever found a source for those.  I have a 164 waiting for one....

I thought one of the problems with the 164 was with the high speed nozzle leaking at idle because of the one way valve that is in that circuit.   I could be wrong with the ole memory bank.

It was an intermittent problem that sometimes showed up in that particular carb.

My ailing HDA164 was all over the place.  L and H side were both way out of whack and responded unpredictability to adjustments.  The NOS HDA137 that I swapped on cured things...

This is a symptom of the bad high speed nozzle check valve from my experience
We should share what we know... someone may learn...
That knowledge can live after us... and that "Pays It Forward".

Yep.  That carb sits on my shelf, awaiting a new HS nozzle check valve.  I don't know of a source for them.

Well I bought the EBAY carb thinking it was new.  Reread the ad and it was pulled from a poulan 330.  Oh well, now I probably have 2 carbs with issues.  Once I get it and inspect, probably time to order another rebuild kit.  :(  Still hoping for the best...

I got the new carb.  Found that replacing it is a little easier if you cut the 2 bolt a little shorter that hold the carb on.  Bad news - still the same issue.  It has a really high idle and the low speed is needle is rich to keep it running.  Thought some more - must be a leak on intake.  Sure enough, starting fluid shows that the the right side looking from the carb is the area where I need to explore.  I guess I need to get that rubber intake boot off to inspect.  This must have happened during my tank/handle replacement.  At least now I have a spare carb and a little closer to the problem.

At least you know how to take it back apart and get to the boot.   I learned a few things the hard way my first time at it also.

The 3450 was one of the first saws that I put a new piston in and used the acid method for cleaning up the cylinder.
