WHY would I have oil in where my flywheel and coil

There's a seal where the crankshaft comes through the block most likely defective. Because the crank rotates through it, failure is more likely.

Give more information. What car, what year model? If there is oil where the flywheel is, chances are you have a leaking rear main bearing oil seal or leaking gear box primary shaft oil seal. Coil packs? They should be there to make the car go.

either a jam up in the bobbin which is preventing the needle bar from coming up, internally siezed up, or the friction belt internally to the flywheel has broken/worn out.

There are a couple of different SU models, the Star Series and the Air Electronics both had an SU (supermatic) model so I'll be general in my description. Firstly remove the needle cover plate and check around the bobbin race for jam ups. Or if the machine has been packed away for a long time unused, then we could assume this is a sieze up. FIRST REMOVE THE POWER PLUG FROM THE MACHINE FOR SAFETY. You'll need to remove the top machine cover and delve into the insides with a bit of patience, good quality sewing machine oil (tri-flow is perfect if you can obtain some, bike shops have it or I got mine from Ebay) and Qtips or something similar.

There should be a couple of screws holding the top cover onto the machine so remove these and then lift and tilt the cover to the back around the lifting handle and making sure you clear the bobbin winder mechanism on the right. Really good idea to take photos with your mobile as you go so you can remember where things went. Now apply triflow to the metal moving parts you can access, in particular the top of the Elnagraph shaft which should have a red mark for oiling point, and the needle bar swing bearing. Keep oil away from the belt/s on the right side of the machine where the flywheel is driven by the motor.

You'll need to carefully clean, oil and gently move the flywheel back and forwards until things free up.

The early 61 has a coil on the right side, and an electronic pack at the left side of the flywheel, if there is no spark it is nearly always the electronic pack playing up, make sure the wire to the coil from the box is a good conection under the small screw, the later 61 has a single peice electronic unit, so this will need to be replaced.

ok follow your plug wires from motor bottom up where they connect and that is going to either be your distributor or coil pack also the transmission fluid should be red and be a long dipstick and the top usually locks a certain way or have a gear looking symbol on it hope this helps let me know good luck

How did you fix that problem. I run into same problem

Under the cover that covers the flywheel on the right hand side there is a connector that is likely unplugged,this grounds the coil when you turn off the key and there by shuts of the motor.If this is not the problem then you likely need a new ignition switch.

The coil pack is located on the right side of the engine (look from the front) under the plastic manifold covers. Just follow the pretty spark plug wires to the end and they attach to the coil pack.
Rate it....

willie05: sounds to me like you have a leaking rear main oil seal.
If the oil is dripping out at the bottom of the motor and appears to be sourced from where the back of the engine and the front of the transmission mate together, that is your problem. Sometimes if the leak has been going on for a while, the under side of the engine and transmission may be covered with oil because of the wind turbulence caused by the car in motion had been blowing it all over the under side. It may take you washing the under side if the motor off or getting it done, to spot the leak more easily.
A valve cover gasket leak will also cause oil to run dow the back of the motor. However, it usually won't get on the flywheel.
Good Luck. Let me know how things turn out.

I believe that year had distributorless ignition, instead it uses a form of coil on plug ignition system.

If you open the hood, stand at the front of the vehicle. Look to the left side of the engine, around the bottom of the valve cover (The valve cover is where the oil fill cap is. The oil fill cap is on top of the valve cover), at the bottom of the valve cover on the left side you will see a series of humps. Those series of humps is the coil packs, the coil packs are all in one long piece held down by three or four bolts.

Take out those bolts, gently pry up at the ends of the coil pack and it will eventually come out. You'll see on the bottom side the spark plug boots are attached to the coil pack. After you get the ignition coil pack off, you will see the spark plugs under where the coil pack came from, the boots on the coil pack sit directly on the spark plugs.
