I was hoping the boot from my 625 would be able to go on the 670 cylinder. I have a 670 cylinder on the way so I guess I will find out soon enough. 272 top end requires too many parts to be worthwhile to me.

Did a little research on the Tillotson carbs that came on this series of saws. I was surprised that the 625 shared the same bore and venturi sizes as the 630 and 670. They all shared the same low speed needle as well. Where they differ is the high speed needle. The HS237/251 that came on the 625 seems to have a unique H.S. needle not shared with any other Tillotson carb. The HS230 that came on the 670 shared a H.S. needle with Husky 281. The HS250 that came on the 670 shared a H.S. needle with the 630, as well as the 266 and 272 Husky saws. The 630 came with an HS225/252/256. All this is according to the Tillotson chart and not necessarily carved in stone.

Having said all this, I have Tillotson carbs here from both the Husky281, and the 266. I am thinking the carb from a 266 would be the proper carb to use after I install the 670 cylinder.
