Wow that is a big port and no oval at the edges to allow the ring to come back in gradually.     I guess that cylinder is toast.

Thats what I was seeing and they had made it to flat at top too. To undo that I would have had to raise it even more to try and reshape it back. Already it had lost torque in the cut IMO so tried without that.

I had a race 166 that was way more before and it did fine. But this cylinder was just a mess from get go when received.

Chit need to find the bigger pic


Aslo folks trying to run a 54mm top on the 36mm stroke in the 5ci race classes is over the size limit allowed. If you get checked it is a cheater saw.  Have to run the 52mm cylinders or ;)

54mm x 36mm 82.447949622cc   5.031283065765201ci

5ci cc allowed.  81.93532cc

Was cleaning up the 2077 cylinder and getting ready to put a NOS piston kit in.   

Doing a much closer inspection.   :o :P

Finally getting back into one of my own saws I had bought thats been a problem child since arrived.
Keep breaking rings 2 times, then finally 3rd time fubarred the whole topend. No matter what I tried cleaning up someones past porting.
Think I just found part of the problem looking it over much closer this time around.

Crankcase split and crank pulled.  :D

Got another call out of the blue from a small engine shop in Iowa.  Guy working on 2083. Needed plastic worm winged gear and clutch springs.

Not given up anymore plastic worm gears to we get a source for 3d making them. Guy in the chainsaw repair group suppose to be making them for us to try and test out.

Clutch springs are just husky springs on the newer clutch and I informed him.

Also told him he might be able to use the metal worm gear on the later saws that had the plastic worm gear. Anyone did this?

I know the oilers are the same. Just wondering if room since different pto seal and bearing set up.
