Question. I have been converting some Robin 24.5cc engines to use on my 1/5scale OV10. They run great and are very light. I have gotten engines from Robin brand weadwhackers, Robin brand blowers, and Makita brand weedwhackers. All of these have been identical engines. They all have a single ring on the piston. I just got a Tanaka model#TDC-2501 weedwhacker engine off of EBay. The engine is identical to all the other engines except that it has two piston rings and has what seems to be much higher compression.

Does anyone know if I can buy a Tanaka piston and rings and replace the Robin/Makita single ring piston?
