Why my Cub 184 Lo-boy does not start right

Hello, I recently purchased a Cub 184 Lo-boy. Whenever I start it up I have to crank it like crazy and it does not fire until you let off the key. Its like you have to get to motor turning so fast that it coasts enough to start it after you stop turning the key. When its started it runs great. Has anybody ever had this problem with one of these? If so then do you know why it does not fire when turn the key and just keep turning it over? Another question is does anyone know where to check the transmission oil on these? Thanks for any advice! -Henry
 
Check the wiring from the starter to the ignition coil. If it uses a contact on/in the starter to feed power to the coil and then run on a different position of the key then the connection for power to the coil during starter action is broken.
 
Fairly common problem, somehow the ignition is losing power while cranking.

It's usually caused by a faulty ignition switch. Some use a resistor bypass circuit, but that's usually on larger engines.

A dragging starter can rob all the power, leaving not enough to make a spark until you let off the starter. But if it spins normal that's not likely the problem.

Put a test light or analog volt meter on the coil primary ignition side to ground, take a reading while cranking. If the power drops to zero, or below about 6 volts (3-4 if there is a resistor), something is wrong.
 
By any chance has anyone changed the ignition switch in the last 70 years?

Put a test light to the side of tbe ignition coil post that is wired to the switch, not the side that goes to the distribuitor. Ground the other end end of the test light. Turn the switch on, Test light should light up. Turn the key to 'start'. It should stay lit. IF it goes out, you have the wrong ignition switch.
 
I read your title as an update on why is wasn't starting. If it starts as you let off the key, there is something in the ignition system that isn't getting enough current while the starter is engaged. Poor battery, starter drawing to much current, or some component that has to much resistance.
 
Thanks for the advice! I will test the the ignition switch tomorrow. I believe that would be whats wrong. Thanks!-Henry
 
If it has a ballast resistor,that is the problem. 60s and 70 Mopars all ran them before electronic ignitions.
