66251 is the block number for the 797/Super 797 but your saw has no DSP valve (compression release) so something does not add up.

In any case, with the gearbox that was is not a 797, the 797 is a direct drive saw.

You may have a Frankensaw, but the lack of the DSP casts doubts on the block being a 797 unless someone has blocked off the port. Remove the cover from the muffler and see what is there.

Mark,

You can have a 797 gear drive. You just have to be creative.

Yup, I was, and found it relatively easy. Now building a 125g, that has a hangup ot two. Mostly making all of the bends and twists correctly with the oil pump rod. Making the front mount can be dine a few different ways and you need the wide chainbrake front handle & mounts.
