THx Bruce, I've taken a careful look at the manual but cannot find any reference to permissible crankshaft end float tollences or any instruction on how to adjust the end float. As mentioned in my original post, I reckon I have end float of 1.5 to 2.0 mm, sufficient to make a distinct clunking noise as I hand force the crankshaft in and out of the crank case....... Just doesn't seem right?
