[SEL] Compression question

[Russell]

Quite some time back I bought two very average looking Hornsby oil engines; a 2 and 3hp types. They came with enough bits to make one complete engine etc ................... Well I have hunted extra bits now and have enough to basically complete both. One will is going to a good mate whom is doing all the work (he has spare time) and the 2hp I will keep. Although not at the point yet of putting the piston back in and seeing how much compression it actually has, (my 2hp) I noticed there was a very small amount of pitting at the top of the bore. Now it's not much and only time will tell if it's even going to be a problem. How ever if it is a problem; I was thinking instead of boring or sleeving. Could I just cut another ring groove further back along the piston; remove the top ring and put in the lower new groove?? This would avoid the pitted area mostly and the majority of rings would be running in a clean bore? Any issues with something like this?

cheers all. Russell
