Piston sizes
Posted: Tue Jul 01, 2014 1:11 pm
While in the middle of my 2 door restoration, I bought a 1275 midget engine to fit in place of my 1098.
The internals look quite good, big ends have been ground to -.010" and the bores show almost no wear however,
the pistons are clearly marked 0.75 suggesting 75 thou rebore.
When I measure the bores I get about 71.4mm (metric mike) which is 0.030"over standard
Would piston have been incorrectly marked? seems hard to believe.
