The outboard wants to only idle for a few seconds then quits. Whether just starting up or throttling down once the throttle goes to "start" to shift gears the engine wants to quit. Any ideas would help. Another question is that it seems to smoke quite alot. I realize it's a two stroke and that's normal but this smokes alot. I'm sure I put the right fuel to oil mix at 50:1. Is there a difference in oils as far as how clean they burn?
