As someone in the thread said, air is power and thats about it.  So a guy calls me and says he lives in Louesiana and is up on Colorado with his coach.  He said it was not running very well and asked what he could do.  I asked him how long he was going to be in Colorado to which he said 10 days.  I told him you could readjust timing, get fatter jets and spend part of the time up there messing with it or he could just wait say 10 days and the coach would start running better as he headed home.  If the motor keeps running but just runs badly, let it do what it will as long as you are heading home soon.  You could twist the dist around a bit but put a mark where it was so you can put it back.  I would also not race anyone at traffic lights up there.  I mean it's all relative-- I'm not as fond of mountains as many people, thats why I live in the sand down here in Florida.  my blood is too thin for the cold weather which BTW someone left the door
open cause it's cold down here.  Retard the timing up there, baby it and hold on til you get in better air, your coach will thank you.

BTW, I do hope those with FI systems do not get too mad at me, I'm not attacking your idea of putting it on-- it just does not fit as a positive option for most of the folks I do work for.  It is very cool to have the motor light up from a cold start and the "sweet Mother of acceleration " does look pleasantly upon FI systems.  I will add though that the first year we did the drag race rally here in Florida I ran Larry sporting a direct port FI system-- I got a hole shot that snapped my neck but the next year I ran JayGee with a Qjet, original motor & tranny and I beat my time from Larry with it!  I'm down with carbs on the straight line 1/4 mile hands down cause I did it!

Thanks Jim for writing this up.  I'm one of the guys debating this issue.  I have a Quad and have had it rebuilt,  and have no troubles with it on how it responds.  I'm in Missouri and it serves me well,  but I would like to use the coach in the mountains.  What would be nice is to know how to adjust the distibutor for the timing and also the carb to run it's best in the mountains.  If I could get that information then I'll try to adjust it when it's time to go through the mountains.  Is that a reasonable approach?
