does anyone know if a large cap dizzy from a FJ60 2F is curved differently than the same stock large cap from a Fj40?

It seems like the advance is greater with the 60 dizzy as the 2F pings hard under a load...almost a rattle when the carb secondary opens up. Seems to be low on power as well.

I have the timing set to fsm standards...7 degrees at 650 rpm, hoses disconnected and plugged.
 
do a search :grinpimp: (this is a very common thread)
