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.
Mine has no points, so it may be the taller one. It is the one that came with the engine.
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 did run two power wires, one for each coil/igniter, with plans to install a switch for runup mag check, but I never installed the disable (test) switch. I think that I can tell that both coils are firing by the rpm on takeoff, and the color of the plugs are similar.
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?
Yes, a gravity system relies on - well gravity, so the carbs need to be below the fuel tank. Not very likely unless you have a high wing bird, and no header tank. I bought an adjustable pressure regulater, and reduced the 3 psi pump ressure to 1 psi for my motorcycle carb setup.
It worked, but still had a poor mixture adjustment (none other than air leaking into the manifold, same as Tracy had)
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:
Those sure are cute, but two weigh as much as a real alternator.
I use the stock alternator- 80 amp I think. twin belt setup from Racing Beat for water pump and alternator, install new belts every five years.
The lawn tractor battery should give over 1/2 hour of flight without the alt. I can buy a new one at any parts store.
Nice looking bird !
Good luck Michael,
