I have this motor and it was running like a charm, but now I'm getting this miss, at all speeds. The miss is not happening with any regularity or pattern, but it does happen from idle to WOT, but not all the time. My carb is clean and just re-built, I have the right plugs, my gas is fresh, I've de-carbed, replaced the coils and ignition parts, and like I said it was running great. Am I missing anything? I suspect it's the condensers, anyone know the tell tale signs that your condensers are going? I'll probably replace it all again, double checking my wires for ignition shorting. I just hate not knowing.
