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.
