I'm thinking of converting a Ryobi 31cc and have a few questions. Has anyone used the electronic conversion kit from CH Ignitions? Any problems with the conversion kit? How does the engine run without the flywheel being that it is run with and electronic ignition? What carb. would be the best to use? I have a Zama C1Q-M33D which is a 12.5mm carb. Would this carb work alright for this? I read somewhere that a guy used the same carb. on this engine and said his worked great. Is there anything I should look out for? I'm thinking about modifying the existing muffler by putting a tube in for the muffler outlet. Anything that can be added would be much appreciated.
