I just wanted to let you know how your “discussion board” helped me resolve a no start on my Rotor Tiller.
I bought a Rotor Tiller last spring that quit running at the end of the summer. I haven’t had time to return the “Tiller” to the store I purchased it from, until recently which I found out the ignition system had no spark .The stores shop said the ignition coil failed and there was no warranty covering the failure. The cost for the repair would be around $ 85.00. Before spending $ 85.00 on a Rotor Tiller less than a year old I contacted my dad who is an Auto Technician to give me his opinion. After talking to a few small engine technicians he could not get an exact test for diagnosing a coil on a small engine. The small engine shops my dad visited said “the coil would have to be removed and brought in for testing on their equipment”
He removed the coil and took it to small engine shop and they said it was not in working condition. He ran a few test on it with his meter and he questioned the coil was bad. So he started researching the internet and came across "Abby’s Guide Outdoor Power Equipment" and found a post by DRLMN1 (Dennis Lemmon) dated May 29, 2005 on a no spark and how to test a coil. My dad followed the test using a 6 volt battery charger instead of a battery and found the coil in working order. After further diagnosis my dad found a “terminal end connection” on what he said “the transistor ignition” not crimped correctly and repaired the problem.
