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

@mweba

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

Very interesting. Mitch comes up with the coolest stuff. Looks like the HDA77 has a venture diameter that's in between the HDA49 and the HDA136/164.

I agree on the 3500. Just get an original HDA49 (they are common).
