Ok I have done a little more testing. Compression checks out good all pretty even numbers. Spark seems good while checking the plug while cranking. I went ahead and put new plugs in while I was there. I went ahead and put all new fuel lines and filter on. Took it out yesterday and it is the same. So I'm thinking fuel pump? ( I'm willing to buy one if someone can suggest a part number or how to test it?) Or tear the carbs apart? It seems weird though it ran fine the weekend before. I parked it inside and took it the next weekend with same fuel and it immediately acted up. So something seems to have just "failed".
