Slow but rough

Hi all
Did a bit of checking with the piston ring gauges we have and it seems that the rings are tight in the gauge but loose in the bore (68.4 mm)...The ring gap in the bore is outside the assembly setting but tight in the gauge indicating it would need a bit grinding off the end but that would make the gap even larger in the bore...I can't really measure the bores apart from at the top. At first glance it looks like the bores are too big. I will clean out the grooves and measure the groove gap against the piston ring next. The pictures show the difference visible to the eye.

Bit better news on the brakes...my son's had bought me a cordless dremmel gizmo so using a felt tip with some fine compound I cleaned up the crusty bores of the wheel cylinders and put it all back together and bled the brakes...no leaks yet!

Off to the machine shop tomorrow to see if we can get this engine sorted out. I have a spare block so if the original is goosed we can try the spare...

Visited the new machine shop where the bores were checked and to my surprise they were exactly as they should be at 68.4mm....However the machine shop man was not impressed with the piston rings describing them as having a finish like a 'Thruppennybit' so we concluded the rings were the problem. So we decided to have the bores honed a little bit and some new rings sourced and start all over again with the existing pistons as machine shop man declared them OK and good quality.
