Hello. I recently purchased an NGH gt35r. I decided to read up on this engine as I know nothing about them. I've read that people are having problems starting these engines when they are mounted inverted. I'm putting this on a stick, so I can go either way, but are these really problems when mounted inverted? I was going to mount it this way, but not so sure now. What has everyone heard about these engines? Thanks for any input on this.
