Got some advice from an old guy awhile back, "breath till you stop".  Worked so far.  :)

Skidder job fell thru. Was a cleanup of another guys mess. Said no thanks. Start Monday on a 2000 acre lot. Mostly hardwood shelterwood work. Bet the crew has never seen a couple ported Efcos before.

I would bet not too.   Which ones do you use most for this type of work?

The stroked 156 is my favorite. More torque than the TW962. If the wood gets big the ported 980 will see some service. Have a few regular stroke 156s to port next.

Efco makes 2 different stroke cranks that interchange in their saws. Cheap and effective.
1mm longer stroke for the 156, 962 and a 2mm longer stroke for the 70 cc saw.

I think the longer cranks started life in the concrete saws and got carried over into the saw line.

Are the cranks hard to get ? if so maybe "stockpile" some for those "rainy day builds"  8)

Both cranks are in production in new saws. The 156 has the short crank, 165 has the longer crank. I think they wanted more cc's out of the existing platform. The base saw was a 56, next option was the 962 (a 2 mm bore increase over the 56). Then the 165 came out. It has the bigger (962) bore and longer stroke.

The 156 has a wide squish, stick the 165 crank in (or easier put the 156 head on a 165 case) the squish drops to .020.
