Using the most-up to-date technology available, to me, my Stamps.Com postal s=
cale. I find that #1&4 are 55grams heavier at 1.697kg, than #2&3 at 1.640&4=
7kg. So the weight variance follows to brand difference. They all look the=
same, flat top and full skirt. =20
Now off till next week to a machine shop with better scales and the ability t=
o fix it. Will be taking the crank and flywheel as well for balance checkin=
g. =20
Thanks to all who responded. =20
Best,

I'm sure it contributed to the roughness of the engine but it ran just the s=

Having the same pistons in the same engine at the same time is surely the pr=

However, I'm sure it's possible to keep a TR engine running with different c=
