I know a little bit about this. I've been running nitro engines for 30 years and have been in the business for 25 of those 30, but the point isn't relevant to the topic so I'll just agree to disagree with you. This is the reason I avoid posting on forums too often - there's always an internet expert that wants to challenge the most benign statements. Back to our regularly scheduled topic of engine tuning.
BTW, I grew up and worked back in that neck of the woods for a long time. You and I have probably raced together on occasion.
