A straight gassed 266 with really nice plastic...blended with a 272xp top end


With plastic & cylinder off...note old style cases.



Note the old twin coil style ignition..


Put a 272XP Cylinder & piston on..had to drill the muffler mounting holes out and use different mounting bolts, had to take off the stock intake and blend a 272 intake manifold, that was about it. A straight forward blend of saw models.
The 266-272 hybrid is on the right with a Chicken Chit 2 Chicken Soup 268 on the left...

As some who have followed these know, It's been a bit of a side hobby of mine to take any and all variations of that chassis and stuff a 272 top end on them...even a 268 or 266 closed port 50mm top end as a plan B. My favorite is a 1978 Model 61 I shoe horned a 272 top end on...fun saw. Documented in detail over at forestry forum...(sorry .. it was before you started this site )

My rule of thumb is if the internal diameters are the same....just use them! (Most are) I think I used the original 61 carb on this. I can't remember anymore all the twists and turns, I do remember switching over the carburetor "throttle & choke" shafts & controls on one of the blends I did...might have been a Jonsered to keep their choke/throttle carb linkage...
