A friend gave me a DT2 he was unable to get running after it conked out on him one day. I took it all apart to find that the lower (the slightly wider) piston ring was in about 3 pieces. I ordered new rings and installed them and the piston would not go all the way into the cylinder. I noticed the piston was scored up a bit, so I ordered a new piston and a second new set of rings and installed the new piston on the connecting rod. Same issue. Piston only wants to go about halfway down the cylinder before it's unable to go any further. I was able to tap the old piston through the cyl (with no rings on) but it was very tight.
Sounds like my cylinder is a little warped. What should I do? Can I hone the cylinder until the piston is able to slide up and down? -it feels like there is a very slight bump by the intake and exhaust ports inside the cylinder.
I have already spent almost as much on this motor as it'd be worth, running. I would prefer to avoid having to take it to a machine shop, if possible, as I am sure that's fairly expensive.
Any help is appreciated.
