Just found this site and wish I had years ago as I know there are folks here that have been working with small engines all their life. In a past life I worked Product Engineering for the Army Small Cal Weapons Lab and was a small arms Test Director at Aberdeen Proving Ground so I know things happen after stuff gets fielded the designers never dreamed would happen and one of my responsibilities was figuring out fixes for those new problems that surface after a system is fielded.
Glad to be here with yawl, thanks in advance for the guidance you can give me.
