My Gutbrod 1032 ploughing I came second out of five very happy

Rather than honing the bore which implies stones and the removal of metal , I’d clean it up with a flap wheel. The Cords piston ring people used to sell various sizes of what appeared to be standard 80 and 120 grit flap wheels on extended spindles to reach down the bore and I’ve subsequently used standard diy wheels with an extension shaft that I think came with some wood boring bits. Clean the bore as best you can and offer up the rings to it and see what gaps you have. If you need new rings you may find that Tarpen economised by using the same sizes as another mass produced engine manufacturer but if push comes to shove there are a couple of firms that will make rings to order - but at a price! As you are probably aware, with a two stroke you not only need compression in the accepted sense but also sufficient sealing to transfer the mixture from the crank case via the transfer ports. That takes us to crankcase sealing including , if applicable, the joint between two halves, the main bearing seals and the joint between the case and cylinder barrel. Two strokes are equally sensitive to crankcase integrity as they are to cylinder compression.
