Hi everyone, thanks in advance for your help.
I have a 15 horse twin with CD2 ignition system. I'm trying to get it going for a friend. The motor starts and dies within a few seconds. I've rebuilt the fuel pump beacause the diaphram looked to be in poor shape when I checked it and cleaned the carb twice and put a kit in it. No change. I did find some chaffed wires on the ignition sensor and charge coil wires so I isolated them from grounding out until I repair them. I did resistance checks on these two components and they check out as per the manual. 36 ohms on the sensor and 514 ohms on the charge coil. There is spark but it appears to be weak when checked with an in-line spark checker.
The motor operates like its starving for fuel but I don't know what else I can check on the fuel side. I don't have anything other than a multimeter to check things with so I don't know how to rule out the CDI box. Could the chaffed wires shorting to ground caus the CDI to fail in such a way as to give a weak spark? I don't want to change it only to find out I've overlooked something.
Any ideas would be appreciated.
