George:
 
Just a confirmation regarding your disribuitor. Yours is infact the old dual points distribuitor form the pre 85 engine? the shortie with the low height cap?  not the later taller one.
 
That is what I am planing on doing myself for my Falconar F-12. I have an 1988 13B but I have a nice rebuilt 85 points distribuitor.
 
Are you using a coil switcher to isolate the two sets of plugs? or are you runing it straight as it was in the car?
I am curious if there is any way to isolate the two sets of plugs and points so as to shut one set off. Dont know if there is any advantage to this other than ground test for function as a pre take off check but just curious.
 
As for carbs, for now I am working on the three 34mm Mikuni carbs set up as Tracy did originaly though I am still thinking of how to get a total gravity fed system from my nose tank. any ideas?
 
for electrics I am planing on dual dynamos each puting out about 20 amps. Tiny little gadgets with an external heat sink regulator.
 
like so:

An O-235 or 320 is also spec'd for the Long-EZ, which my bird is a modification of.  My airplane weighs the same and has about the same power as the O-320, more power than the O-235.

I have a 1985 RX-7 13B for power.  I installed it after about 40 hours on a ground test stand.  Never did need any parts for the engine, I did replace my psru with one of Tracy Crooks. My engine was used when I bought it, no rebuild.

I use the stock distributer for spark - never had any SAG.  Have an old Dodge truck 2bbl carb, which I modified for mixture control. I do lust after a RWS EFI setup, as I am comfortable with electronics, but it flys so nice, I leave it alone.

If my engine ever needed any work, I would have to do it, and if it ever needs any parts, then I will have to find them, but so far, almost ten years, over 500 hours, it has not needed either.

I hope that your luck is as good as mine.
