• You've done an admirable job with both the guitar and instructable. I have also reviewed the amplifier/speaker instructable. Your work in both design and execution is impressive. Very well done!

Hi, Luca Gerda! I'm a professional designer (college and everything!) and there is nothing like stumbling over a technique, then putting in the effort to make it yours. You should be proud! I enjoyed this instructable. Thank you.

• Have you tried U.S. Carburetion? Even if a conversion kit isn't listed, give them a call. Also, they occasionally show up on Ebay. Good luck!

That's OK, if it's convenient, but not nearly as efficient as one might think. NG has less than half the energy of LP for a given volume at standard pressure. In addition, the amount of usable energy from NG is only about 85% as efficient as LP. That is, it takes more than twice the volume of gas to run your engine, and it will produce about 85% of the energy from the generator. That would make the cost differential more like: if NG cost \$2 per unit, then LP costs \$2.40 per unit. (It could be any denomination of currency, e.g. NG 2 Euro = LP 2,40 Euro).In my area, LP is cheaper in relation to NG, so per unit of electrical energy produced, LP would be cheaper. That...and there is no NG service in my area, so convenience isn't even a deciding factor. In your area, NG may indeed be ...
