I have a 1982 Honda CX500 trike, put new rings, rebuilt carbs, compression on both cylinders is between 150-160. When it's running, you pull the left side plug wire off it quits running but when you pull the right side plug wire it stays running. The right side plug is wet and the engine backfires. No leaks that I can tell. Have been through the manual several times and haven't found anything amiss with the set up. Help!!
