I will buy a filter now that I know it has solved the problem. I have run the fuel level down 3 times now. This was before the filter change just in case it was bad fuel. By down I mean 1/2 hour below empty. Most of the stuff should be gone.
Good to hear. I hate getting bad fuel - it's a great way to ruin a weekend chasing around trying to figure it out. Then having the second filter clog up the next weekend is my usual result!
