We have a new person to gasoline asking for tips. My tips atr not directed at those that want an argument. The beginners can heed the advice of the experienced or not. Their choice. I have seen long time IMAC guys at the field recently have stopper problems. Almost nobody at our club that I know of use them anymore. Like I said, we have Ethanol in our gas. You would not use a Gas stopper in a glow fuel set up would you? Well, that is what is going on in my state. Lucky you, that you have better gas than we do. My solution- screw on cap tanks. A much better system. A word to the wise should be sufficient.
