Kelly and Roy,
Well...you can't get much cheaper than that! How simple! I'll get a screen today and modify it. Thanks for the tip and pictures.

I'm glad to hear that plugs can lasts a long time. I was under the impression that plugs had a short life span. Just one of those nagging things that bug you until you find out different. I have seventeen flights to date and the engine is running great. I changed the fuel system as you suggested and everything seems fine.

Thanks,
Keith
