    That's great news! What carbs are you using? You may run in to jetting issues.

    Running c model carbs also so should be alright but these carbs need a little bit of tune but not to much of a biggy

    Hi All,

    Thought I'd tack onto this thread rather than start a new one.

    I have also swapped a C engine into an A frame and after much swearing and head scratching I have spark (Thanks Kiffsta). I used the spark plug for cylinder 4 to check for spark. I didn't check the other plugs at the time.

    The problem I have now is I can only get spark from one coil at a time...

    I started the bike up today and noticed it was running rough. A quick check of the pipes and 1/4 hot & 2/3 cold. Okay, might be a dead coil, but since I had another C loom laying around I thought I'd try the quickest test and swap the relay at the end of the wire that has the coil wires. Bike wouldn't fire without choke and the exhaust test showed 1/4 cold and 2/3 hot...WTF! I then noticed I'd accidentally partially unplugged one of the wires going to the coil that feeds 1/4. I plugged it back in and tried again. Bike fired up without choke, but was running rough again. Exhaust test...1/4 hot and 2/3 cold! I had a look in the manual and it talks about arcing distance and whole bunch of stuff that might as well be written in Greek (I don't read Greek BTW). Not sure why one coil works when the other doesn't and vice versa.

    Any help would be greatly appreciated.

    No idea. The only help I could give would be to scratch my head for you. :lolsign:
