What are the symptoms of a faulty starter switch? Sometimes the starter does not engage until the switch has been turned off and on three times. Strange about the three, which seems constant. Most times it starts first time.
Could it be the ISC motor or idle switch with CFI?
I did have the starter switch apart some time ago and found that it was packed with grease which had hardened.
It is a rotary switch but there is one contact which is a pressure switch. What does that control?
