[AT] More on Rebuilds

[Ken Hough]

Hi folks,
Quite a few answered my plea for help. Thanks. Unfortunately
no one answered my questions. This engine is in a 1917 Duplex 4 wheel 
drive truck. It appears to be the same Buda engine found in tractors of 
that vintage:
We are oversizing the cylinders .040 to remove damage It turns out there's 
a GM piston that has the same wrist pin to top distance and are available 
.040 over. 
1.Has anyone used these? 
2.Has anyone had custom rings made while using original sized pistons in 
an over sized bore? 
3.How important is the bottom ring? 
4.Is the bottom ring a guide or an oil ring?

Please answer if:
A. You have done a 4 cylinder BUDA rebuild
B. helped on a 4 cylinder BUDA rebuild
C. Know someone with this vintage BUDA engine 
So not to clog up the mailing list reply here>>k4sb at niia.net
