Thanks gents for the info. I noticed that ACKOPTER began asking similar questions on numerous threads about a year ago. I hope someone was as helpful as you have been. I have emailed the person you directed me to, sure was a lot more help than local club pres who said 'go to www.floridaclub40rules
. If the number select is in there, someone please point it out to me. But as I said, AC has already given me concise info.
I would like to mention that after questioning LHS owner about planes, I opened NIB engine and inspected it. The engine head clearance or space is just like 'earlier' version but the carb has offset needle like 46 (I like that). When I asked owner if he heard of discrepencies both he and his assistant answered a simultaneous 'never'... comedians. I remember a remark made years ago in RCM that the (unmodified) 40's were just as powerful as a 60. Well that was then and today there's no comparison. And on this subject, I compared my old OS 46 FX next to my new TT. The OS looks to be a little meatier but I have not weighed them. Don't want to be disapointed - should they be same or 46 lighter.
For kicks and giggles I would like to see an all stock 46 race against the TT 40 in a flat line. Same plane, fuel etc. Would be interesting, especially if the 40 won!
