There are many stories just like this one. What is that old saying, "pay me now, or pay me later"? Well, flying is expensive. It took me a long time to come to the conclusion that if I wanted to fly, I was going to have to pay at one end or the other. So, I choose to have the convenience of filling up at the airport with 100LL and take that problem out of the equation.
It will be a great day when 100NL (no lead) is available and the lead problem with valves and plugs, is also removed from the equation. See N64KR at http://KRBuilder.org - Then click on the pics? See you Oct. 4 and 5, 2013 - KR Gathering in Mt. Vernon, Il ? MVN Daniel R. Heath -?Lexington, SC -----Original Message----- I replaced the fiberglass wing tanks in my KR-2 with welded aluminum tanks. Ethanol in the mogas, that I was trying to use, was dissolving the Vinyl Ester resin rather quickly. Rubber components in the carb were being hardened and would not seal. (Lots of fun and excitement when the carb overflows while the engine is running.) Now using 100LL exclusively. The fuel system is good to go now. The tank change out and carb rebuild cost about $1500 and six months down time.
