What saw did the HDA77 come from?  Did Mitch have to modify the carb or change parts for it to work on the 3450?

I went searching. Seems to be a 77a 77b 77-1 etc.   http://wem.walbro.com/walbro/product.asp?CategoryName=Titan+50&Series=HDA&partnum=HDA-77-1&GroupName=Chain%20Saw&FamilyName=MC%20CULLOCH

From Macs it looks like.

Is hd77 any better than the 137 or 164?  Or is this the next best thing?  Just bought a 3500 with no carb :)

3500 you just need the oem 49 carb with small boot. 

I dont know why Mitch did the switch. Maybe had a problematic 164 carb  ???
