Thanks G.F.Reid;

I know what you mean. I hate cleaning that glow fuel, and no matter how well you think you have done, it seems to creep into something. The only saving grace for this plane is that I have fiberglassed it and the markings etc. will be painted on. It also will not be an every day flyer( if I get it up and down in one piece:-) ). Too many dam decisions, I guess everything in one way or another turns out to be a trade off. I think I will still try to make my own muffler and run it out the sides, and if the thing does not perform the way it should.......... well I guess that will make the decision for me.
Thanks again I value all your opinions.
Peter
