Bob E, I agree, wire connection and function are critical! As a matter of fact, I make sure as Charlie does with his cubbys to clean and lube with grease. I have found that a starter solenoid from an '88 Ford Crown Vic with the 5.0 E.F.I is a darn-near perfect replacement match that works!
So, the other day I had my 1450 apart, the heavy cast iron grill housing so distinctive to the last of the "true" IH Cub Cadets, was removed for cleaning and a snubber shim adjustment.
Anyhow, I had the ground wire disconnected that leads to the starter mount bolt. After my adjustments, I wanted to start my 1450 so observe any change in operation vibration, when I remembered the ground wire disconnected. I think it was Hydro Harry, whom, a while ago recommended having another ground wire to help in solenoid "clicks". I have that extra wire connected between the firewall mount and frame, leading up to the engine tin bolt below and to right of the rectifier. I hit the key and the 1450 roared to life instantly with out the main ground wire attached.
Perhaps this extra ground wire is what you need concerning the IH Cub Cadet Quiet Line series?
Dale, I have the most common paper filter for a gravity flow filter from Napa, and my 1450 seems to operate fine, however I have not yet let the fuel run down low to see if it still passes to the Carter #30 carb yet. Still on the fence about it. I think the small red Briggs screen filter might be what is next in the future.
