This morning I cut the new cowel for my Venus II. Came out pretty good and I think I'll get plenty of air flow through. I cut a slot larger than necessary for the muffler on the bottom to make sure I have adequate cooling. Got a couple knicks in the fiberglass and plan on painting with a nail polish the same color. Also, wish I had worn a long sleeves and put on my respirator as the fine fiberglass dust went all over the place and it itches
