That's just way too funny!!!! I don't mind plumbing when it's new either but the one house built in 63 was A thrill, everything from the main to the bath tub wouldn't seal so it was always dripping when you were working on something.
Tank plumbing is another story though, I would do all your plumbing and covering if you would do all my sanding. I have been known to mention before how much I don't like sanding.
Brad got right to the point and someone else mentioned crossing the fuel lines, I have done that A number of times with my three lines, either not marking them when I assemble the tanks or forgetting what the markings meant, even done that with color coading too.
Most the time when I have A bad line inside the tank it is broken or has A hole in it right at the spot where the brass tube ends and the line begins. The last few years I have been soldering barbs on the inside brass tubes and smoothing them out with A rubber wheel and this seems to have cured that little problem.
I have had poopyugler in my carb before but most the time I have found A broken line inside the tank.
Do the easy thing that Brad said first and if it isn't crud then go straight into the tank. I keep extra caps and plugs in my building box just for those nasty little problems.
I love sanding!!! You can get a piece of wood to be any shape you want by magic of sand paper. I will sand things all day and get them to look perfect. I will happily trade with you. I should have mentioned that new plumbing is enjoyable; it's fixing plumbing problems that I don't enjoy, or adding new things to an existing old system.
I have different colored fuel lines, so there's no chance, well a tiny, tiny chance, that things are hooked up wrong. I don't doubt there's a problem inside the tank, or with the cheap plastic bung plug provided. I'll also flush the carb, sprayer, and needle valve.
I think the engine was hot from tuning at full throttle, and probably because I wasn't taking breaks between flights, although they were short and not with lots of throttle. I am running 10% nitro and a medium #8 glow plug. I used the tach this day while tuning; got 13,800 rpm's peak, tuned it down to about 13,200 with the needle valve.
Nate, by the time I'm ready for those kinds of engines, I imagine I might enjoy trying to fix them. At least I want to keep this idea in my head as I progress towards some pattern equipment.
