Found a local guy wanting rid of some 066 parts cheap. Newer 066 parts- decomps and poly flywheel types.
So we agree on a price, I drive down to do the exchange, a small token amount of cash in return for a fairly large cardboard box full of bits.
Amongst the bits was at least one "complete" 066 with the cylinder still attached, intake system attached- just missing a muffler and all the covers- so it got picked on first.
I should have taken photos of the rest, but the cylinder interior was mysteriously clean- apart from a grey/white coating inside the transfers. The piston had some scoring, but the top of the piston had metallic debris imbedded in it and pitted to hell, compression was way down and overly worn rings the culprit.
Cleaned up what I had, almost thinking running problems lead to past user/owner using starter fluid in an attempt to fix it with a can? (to justify the white deposits and clean cylinder interior- no carbon!) sanded up the piston, new rings, forgot the base gasket and put it back together.
Checked spark- was none.
Changed coil for another 1314 one, no spark. Top mounting bolt was stripped out- so I replaced it temporary with a longer 5mm screw that catches some thread- replaced the lower one with 6mm.
Still no go, no go still after around 5 coil swaps including the one off a known running 066, swapped plugs for known good ones, swapped ignition leads for known good ones, disconnected kill switch wires.....
Still no go.
It was about then I started thinking, if the bolts were loose/ stripped and the coil could move, could the flywheel rub the coil and booger up the magnets?
Swap 1217 poly flywheel for another 1217 poly flywheel- use original 1314 coil and we have spark! Connect kill switch wires and we still have spark!
Prime the carb and the saw runs! Is almost worth a you suck post...... maybe later.
Bad flywheel taken out- note the rub marks on uppermost fins.
Back of bad flywheel.
"New" flywheel fitted and coil held with irregular bolts!
