Bravo, very well said. And no I took no insult by it as I to know there are alot of so called "mechanics" out there that don't have the wherewithal to be open minded to different concepts. After all an A&P licence is just a licence to learn.

Hi all I'm new to this forum and am currently in the planning and setup stage of building. I just read this post and I didn't understand the reply by NICEEZ, "A&P educations are fine for working on certified engine's with absolutely no deviation because once it has been altered things start to change quickly where the normal everyday A&P will not be able to figure it out" What kind of alterations or deviations would make an aircraft engine become so mystical that "I" couldn't figure it out? LOL I'm not offended by this so it was not taken that way. Great forum. In response to the original post on the engine problem, You said you "checked" the plugs and they "look" fine, In my humble "certified engine" 11year A&P experience LOL I would bench check the plugs firing under pressure and take a real close look at the ceramic on both end. I've seen a fine crack in the ceramic insulator cause this same problem. Works good cold but when warms up missfires. Just my opinion. Again great forum take care all
