Magneto coils are polarity sensitive .
Have you installed it right way round ?
Usually marked "engine side"

Question. Did the new come with the high tension lead or did you reuse the old one? If reusing the old lead it might be the problem.

Take off the muffler and peek at the piston.
Or peek at the intake side if you have the carburetor off, you will likely see nothing good.

First check the cylinder condition as Fish suggests.

Following is assuming the limiter caps have been removed and is the initial carb settings.

: Turn the high speed screw H (1)
clockwise until it is firmly in its
seat.
: With the high speed screw H (1)
in its seat, give it 1.5 turns
counterclockwise to obtain the
basic setting.
: Turn the low speed screw L (2)
clockwise until it is firmly in its
seat.
: With the low speed screw L (2) in
its seat, give it 1 turn
counterclockwise to obtain the
basic setting

These carbs are sensitive to adjustment, a little bit goes a long way!

Does anyone have a diagram of where the fuel lines fit as I have just discovered that the primer bulb had been bypassed because it was faulty have now fitted new primer now when I try to run the engine after priming it runs for a few seconds then stops know carb has three connections for fuel line the tank has a high and low connection
And one goes to the air filter as a breather but cannot workout which connects where
