I have recently bought a johnson 150hp v6 2stroke outboard. when i first got the outboard it started no bother. now its sparking but wont start it is just back fireing.

Any ideas what could be causing this?

Did you do anything to it between when it was running fine and it starting backfiring like change the plugs or anything else. If so then double check your sparkplug wires for the correct positioning. If not then pull the flywheel and check for a sheared woodruff key or loose/broken magnets
