Thanks for the description. I've been pondering what to do, since I'm running a 41fx, so the needle valve is also in the back, and I'd been looking at the debating what the odds are that I'd be able to pull the fuel line without scorching my fingers on the engine. So I've been debating some sort of valve or something. (Now, the obvious question of course is why they show 2 dots on the planes in their pictures).

Sorry to sidetrack the thread, I'd just seen several references to fuel dots and had been wondering how they worked.
