This gen has a oil level sensor that will short the "primary" of the
ignition coil as well as a spark enhancer that is called a CDI unit but
the drawing does not show a Capacitor in or near it? I hope this helps
Where did you get your replacement coil Colin?
New coil and spark does not equal you must have spark,, have you check your spark plug, and have you check your condensor is properly working. There is a point where you need to see, make sure the contact point is appropriate or else it won't fire

Check the switch on /off is not faulty try taking the wire off the switch that goes to the motor mine had that problem (lot of dodgy switches fitted to them ,make sure the choke is closing on fully.check spark plug not fouled up with carbon.
There could be an issue with the oil sending unit, spark plug boot or faulty on/off switch. Easy tests. Always use a new plug for testing. Unplug the oil sending unit wire and retest for spark. If spark may need to change the oil or low oil. If still no spark, leave the sending unit wire unplugged and remove the boot from the plug wire. Insert a short piece of paper clip wire into the end of the plug wire and hold near metal of the engine for test. If spark, replace boot. If still no spark, unplug wire from on/off switch and retest. If still no spark suspect faulty coil ~ redo all tests using old coil. If still no joy return new coil for exchange. I use a growler to test coils(growler used for testing armature for short, place one leg of coil on each pad of growler and activate growler for short burst). Good luck.
Have you checked spark for sure? 1) Spray WD-40 directly into carburetor If machine has spark, it will fire 2) Is exhaust port clogged with carbon and dirt? 3) Get new spark plug Pull out old spark plug Put spark wire on plug Hold spark plug wire with fingers Put spark plug threads against metal opening where spark plug came out. Metal to metal Pull cord or push starter Look for spark between metal
First check the surface between the rotor and the coil and make sure there is no rust. If there is take some fine emery cloth remove the rust from both the rotor and coil. Use a noncondutive cleaner to remove any metal particals. If you remove the coil you can use a standard business card to reset the gap.
After completing this process if it still does not start check the plug and make sure you have a spark in the plug gap. You can test it by removing the plug and reattach the plug wire then lay the plug on the head and try starting the engine. The spark should be a bright blue. If you do not have any spark recheck the plug gap. If the spark is a red color your coil is weak and needs to be replaced.
Are u using the spark plugs that the manufacturer recommends. I can suggest you one thing, you can test the coil when it is cold and it tests okay resistance values okay, but sometime when it is hot the coil shorts, and I have seen this happened check values when the coil is hot. Check resistance for the primary and secondary coil windings and record when coil is cold and when coil is hot
Hi i have the same unit, i believe that this is just after fumes that actually smell very much like petrol. As this happens to mine as well and the cap is a very tight seal. Its very much like the smell of an old petrol lawn mower.
Do you know which way round the 240v plugs go.... for instance, which pin is positive (live) and which pin is ment to be negitive (neutral).
As you can put the plug in either way it just seems wrong??
POST SOLUTION HERE THANX
With your model number I could see if it has a low oil safety switch I have seen them go bad (check your oil level )
With all wires un plugged from the coil you should have spark
if not coil is bad .
Use another spark plug to test for spark, ground the side of the plug by holding it against some-ting metal on the engine , spark
plug wire hooked to the plug. leave a spark plug in the cylinder
head so gas wont fly out and hit the test spark plug catching fire (seen it done).
Hi Freddie ignition- to- flyweel gap means flyweel magnet positioned under the ignition coil armature.Remove the flyweel.Check the flyweel key(if it is sheared off install a new one).Remove the ignition coil.Clean the flyweel magnet and the ignition coil armature.Check the ignition coil wires and terminal to have continuity.Remove the breaker points cover,check the condenser and breaker points(they should not to be burned).The ignition breaker point gap and ignition-to-flyweel gap is 0.020" and the spark plug gap is 0.030". regards savumihai71
