When i start it if i press the gas after letting it idle back down to normal the rpm goes down instead of up and it sputters a lot... After it runs for a while it stops doing it. at first we thought it was the 5 year old gas it had in it... but 7 full tanks later its still happening.
If anyone knows what this could be please let me know.
Is this throttle hang?
No, this is not throttle hang. As everyone who posted suspected, it is a vacuum leak. You need to check the hoses or gaskets for leaks. One good way is to spray carb cleaner (or propane gas) at the hoses or gasket areas when the engine is running. If the idle changes (goes really high or really low), you found your leak.
