Engine used to be easy to start but would fall flat after about a minute wide open. Local shop replaced the CDI unit, then the stator, then the fuel pumps and cleaned the carbs, then replaced all fuel lines (I ran it for a while on an aux. tank to no avail). Now, it is really cold natured and takes a while to plane out. It never gets to full rpm still yet. It seems like it is something electrical and not fuel related, but I think the shop here is just guessing at expensive parts to replace. Does anyone have and theories as to what could be wrong. Thanks in advance.
