346 porting

[Craigb]

First bit of porting. I’ve kept the numbers the same after a gasket delete but I’ve widened the inlet and widened and flattened the exhaust ports to 65 70% of the bore. The lower transfers are ground to match the case and smoothed out internally. All the ports were left rough except the exhaust which was polished the best I could without proper polishing tackle. Thank you spud for the advice along the way.

It should go well if it is anything like the one I did for myself....and others.

My 346 is my "go to saw", I was using it all day Monday ringing up a few tonnes of Ash and Pine...lovely saw, so punchy and revvy compared to most.
