Capt., last time I ran tat FW I was geared at 4.2. The was the next race right after the sizzler. I was able to keep up with Mark Brown for a good portion of the main (took myself out). I think 4.74 is a bit too high for the size of FW. It is very odd that you burned it at 100 deg. though. In my experience, once a motor starts to burn it is usually gets pretty hot from the "burning". Sorry that happened to you. Maybe it threw a wind...
