Way to go, Dick! It will be interesting to learn what makes the difference.
My guess is local law enforcement may pay you a visit about the time you get the 5th carb dialed in........ LOL!
Best of luck,
Tim

The ratio on the drive is 3 to 1. I know that the pump is made for a normal operating conditions of 2500 RPM at 2500 PSI. I directed by concerns on the speed of the pump and the restrictions of maintaining a solid flow of oil without cavitation to the pump. However I may have gone to far the other way as the trade off on volume is pressure. The 3 to 1 will now translate into high pressure. Hopefully that side of the system can better stand that overload. Time will tell. Again I just want a load that will let tune close enough for final real life on the water tuning. If it can stand it then that will be even better.
This is more of an upload test, however I will share with you what I have done while waiting for some good weather.
Just for curiosity sake, I pulled a coil to check the resistance of the primary and secondary circuits. Sometimes you wonder what were you thinking. Just over thinking I guess. Anyway my findings were that the primary checked out fine. Checking the secondary, coil tower to ground, ugh where is the ground. Its not the wire coming out of the rubber boot? I know that, that's to take a cracked coil short to ground. OK, the primary and secondary share in internal connection to the same coil (-) terminal.
Having checked the specs on the coil and the voltages of the primary circuits, I went looking for a lost spark 2 cylinder coil. I came up with a coil from a 2 cylinder motorcycle. A good size and specs fell with the range of the ADI system. I know that with a lost spark system, the lost side fires at a lower voltage because of no compression. Given the numbers on the secondary output of the coil, I think it will work fine, both at the same state of compression. I know that with a test board on the coil, both leads will free air fire a 1/2 inch gap. So I made the conversion.
I know that the system I had installed will not fire both plugs when primaries are wire parallel. I know that it fired both plugs a good 1/2 air gap wired in series even with the first coil secondary finding ground thru the second coil primary. I have ask the question how does this impact the total system operation when running under load and not been able to get an answer. Thought there might be some EE out there that could sort it out.
Very clean and sanitary installation. Looks great!

I dont know why, but something tells me its going to be a bit loud !!!
happy new year
hows the dyno test coming?
and the EFI?
I`ve been wondering the same. I`ve been amazed with this engine from the start.
