ensure they stand proud
0·050-0·152mm

new
pistons to the connecting
rods, securing in position
with
the gudgeon pins
and
circlips. To facilitate this operation heat the
pistons
in
hot
water. Ensure the
'fro

mark on
the piston crowns are facing forward.

appropriate
liners for gapping,
which
should be
0·17-0

followed
by the
