[SEL] piston rings and bores.

[peter ogborne]

I just rebuilt a small single cylinder ,four cycle engine. .....short cuts 
,don't take them ! Because i could not readily buy new rings i made some ,no 
problem there but i did not take the glaze off the bore. When reassembled 
there seemed to be lots of compression and start up was easy . After an 
hours run absolutely no compression...first thoughts it was the valves . I 
did the usual and shot some oil down the spark plug hole....compression 
!That eliminated the valves as the problem . Pulling the barrel off and 
examining the bore showed considerable glazing ,there was evidence of blow 
by ,oil coming out of the breather. So now it out with the hone
