I've been having this same starting issue for about 3 years now. The engine runs really well, but i have intermediate starting issues. The engine will not crank, no click when turning key. I can hear choke engage when I push key. To try and solve this probelm, I've replaced the following in the last year......Starter, Ignition Key Switch, solinoid and new battery. I clean my battery terminals and ring terminals every year. I seem to experiece issues most when it rains or if there is moisture in the morning.....but not all the time. Any help would be apprecaited.
