Chainsaw Repair

Pub crawl?  Nah,  we'll probably settle down for a quiet meditation,   then some nice vegetarian food.   Two saws will be cutting for five fires.  It'll take two or three days before it's all extracted, cut,  split and shifted.  The 154 will get a lot more work than it normally would. 

OZ vs New Zealand.  That's a bit like mistaking Canadians vs Americans.   It's always been a joke down here that Americans think NZ is attached to Australia.  There is a friendly but fierce rivalry between Kiwis and Aussis.  The word "Chap" in NZ is sometimes used straight,  but often with some mild humour,  a comment on Englishness.

Back to saws.   
I did look in the 254 exhaust port first.  Seeing the scratches on the piston,  I went ahead a pulled the cylinder.  I hadn't heard or thought of pressure testing for leaks at that stage.   On that point,  what's the easiest way to set up that pressure test?  The input and the plugs.

How does one assess the bearings without splitting the crank case?  The gudgen pin rollers I haven't got super clean yet for a look,  but my finger nail may feel some pits.  The big end bearings I can see the ends of the rollers and they are rolling in their cages OK and look clean.  I don't know if this usefully tells anything about big end wear,  but the side to side play at the top of the con rod is about 1.5mm.

Cheers,
Gregg.
