I don't know if this helps or not. I had a 49 that could not get adjusted. After pulling the high needle and taking a closer look the very tip was broken off in the carb. The previous owner must have been doing a hulk imitation when adjusting the carb.

I thought I looked at that but will look closer. Thanks for the tip.  ;)  :D

Having troubles with my first HDA137 carb.    Wont fatten up on H side no matter how many turns out. 
Reading in service manual thinking some kind of blockage somewhere in it. Havent tried ultrasonic cleaning yet.

Was comparing the H and L from the HDA164 and this 137 and the H was a tad different after the metering point. 



Update

Tip looked fine. 

Took carb cleaner with red tip and sprayed through H and L and then the other way around. The the other way from outside in.  Once had good flow and looked ok.  Put it back together.
Put in saw and tested during this dang ice storm.  Dropped 26 degrees since morning.

Anyhow perfect like it suppose to be now.   Took her to about 13.6K and she didnt keep climbing like before.

137 White on both IIRC.

Thinking this newest 3750 has the 137 too. Plus 3 shoe and front exit muffler cover too.  2 in a row like that.

I didnt want to pull carb off to see. But it had the white plastic impulse on top of carb.

The 2 NOS carbs came in and were both HDA-137 like I was hoping.  8) 

They were being sold as HDA-164, but looking at above pic and what we learned in this thread, I figured 137's.

HDA 164/137

In dire need of a good 164 or a 137.

Been fighting with this ported 330 since last year and started accumulating parts for another only to realize both of my spare HDA164's are bad (86-654).  Well flip me runnin.

 Really don't want to resort to a hda49.

Does anyone have any spares?

Tried the suspect carb on a good runner and issue vanished. ???

I think my issue may be lateral crank movement....which doesn't make sense considering the condition of saw.

Please disregard my plea for carburetors.

Just got around to reading this. Merged with past HDA137 HDA164 carb thread. 

Let us know what you find out was wrong with the 330 someday when figured out.    @drumbum

Just found the problem, (I think anywho...).  The cylinder mount area on the case was not machined correctly from the factory.  Don't know how I missed it the first the first time I assembled,...but apparent this time; (shows up a lot more now after running with gasket delete).

I sealed it with permatex aviation IIRC when I assembled with my ported 54cc cylinder.  Need something thicker... maybe no.1 hardening or no.2 non hardening.  Maybe some of that anerobic stuff.

Matched the case the cylinder transfers this time.  Don't think I did a timing advance on this one like the saw this jug came from when upped to 60 cc.

I originally got this as a powerhead, minus bar cover, in very low use condition.  Must have been a warrenteed saw.
