I am aware that the mid to late 70's model engines had a high top ring grove that would fail because of carbon build up. My question is did that extend to the 1981 115hp engines as well? Or when did they change the design of their pistons before then? Thanks

There was some discussion about the high ring groove pistons just recently. Have you tried the 'Search' function?<br /><br />c/6<br />Hooty
