I got a flat bottom 14' river boat for a great deal and the engine i was told would start but wouldnt stay running. I suspected fuel so i changed all the fuel lines and replaced the fuel water filter, put brand new gas as well as rebuilt the carbs. Once i get it back together I find out there is no spark from either cylinder. Compression is 120psi/ 110psi. I bought a DVA and tested the stator which seemed okay except one reading black/white to white/black trigger wires resistance was 48 ohms and 1 manual states between 10-20 ohms and another says around 40 ohms. I checked the ACV from the orange power pack wires and was not receiving any voltage at all. The power pack was replaced before i got it but after it stopped running. So im suspecting it could still be the stator but could also be the power pack. Any ideas would be appreciated

Go to cdielectronics.com and use their free trouble shooting guide. It's easier than one of us typing it all out.
