Been using NGK plugs in air & water cooled aluminum heads for over 30 years, NEVER had one seize. Anti seize is not a bad suggestion, just not necessary with a NGK IMO. A "baggie" is simpler to set up than a hard tank. One single fuel line, no clunk, no air possible in line, no vent with the potential to leak during maneuvers, no odor in the trailer or house from the open vent & no need to plug anything to prevent odors, no need to drain for the same reason. Being a beginner, the OP has to learn something, anything......a "baggie" is just one more piece of info for him to learn about, even if he chooses not to use it.....I've been playing with nitro models of all sorts since about 1959, gas since 2004. I have set up MANY nitro & gas fuel systems. For gas, a "baggie" as you call it is much simpler & more reliable - for me. Not saying it's the best for everybody, not saying anyone HAS to use one, just one more option. Just saying there are different ways to set up a fuel system - " If you do what you always did, you'll get what you always got." That is why I would suggest it to anyone, not just a beginner. Dirtybird, if you want to turn this into a "your idea sux, my idea is best" thread, then you defeat the purpose of any forum - which should be an open minded exchange of information. I hope I have answered your questions intelligently, without offending you. I did not take offense to your question about a "baggie", although it struck me as somewhat antagonistic. I will apologize in advance if I misinterpreted your intent.
