Finally got the cylinders off today, have a (tomorrow) morning appointment with Robert Grauer in San Jose to take them in for inspection, rebuild, etc etc.
Liberal amounts of PB Blaster to get the exhaust nuts loose, common sense with removing stuff, the photos in the Clymer book and empty egg cartons, ziploc bags and lots of labelling to hold all the various bolts and nuts. I wish I'd taken more pics, but my hands were pretty gunked up.

|found this guy deep within the fins|
|the glove knows..|
.. how to keep garage crud out of the combustion chambers.
|this was as far as it went, initially. |
Had a heckofa time getting them off. Stopped this side, went to the other. Asked Tony to finesse it as I stood cursing and kicking stuff on the other side of the garage. We more or less had to push the four long bolts apart to get the cylinders to slide off. The threading kept catching, towards the cylinder head end. Pain in the BUTT.
I don't have a photo (but should) of how I got the piston pin off, but it involved a hairdryer and about 5 minutes of blowing heat on piston. I hope it works well in reverse.

|completely BROKE my fuel filter trying to take gas line apart ||.|
|and then, just because I didn't want to stop, I took apart the air filter case and the starter cover. Just to see it more bare bones (and to clean them.) Also took apart the choke cable assembly to check it out. kind of cool. No pics, got dirty|
