i'm not sure if those of you whose fsj's had trouble starting when they were hot ever solved the problem, but i thought this might help. i ran across it when i was looking at the http://www.amxfiles.com/resource/tech/timing.html , which there was a link to from the ifsja site. i just cut/pasted it. hope it helps some, just a thought.
--- Generally, the more advance the better, up to the point where you hear pinging. Initial advance "at idle with vacuum advance disconnected" should be in the 12 to 14 degree range. You can try more, and when the engine is hard to start hot then you know you have gone too far. If you get pinging at high rpm it means you have too much total advance. If it pings a little and then quits as rpm continues to increase, then the advance may be occurring at too low RPM. Generally all the advance should be in by 2500 to 3000 rpm. ----
