Hello to you all,
I have been given a Hayter 30" cylinder mower, its a beast with a 3 speed and reverse gearbox, the trailed roller and seat and it also has a rotary deck that can be swapped for the cylinder.
The mower itself is in a really good condition but the engine is a non runner, its a Swiss made 7hp MAG engine.
It has good compression, a reasonable spark and fuel gets through to the cylinder when turned over (pull start).
I have managed to get the engine to fire but not run so I suspect the timing is out, the detonation does sound out of sink with the pull stroke.
I have had the stator access cover off, but not the flywheel as I have to make a puller, and the points and condenser seem reasonable, no timing marks visible.
The plug seems a bit short for the reach.
The info I am after is:
The correct plug and gap?
The points gap?
The timing BTDC?
And also I might as well have the tappet clearance if its available?
I will post a picture if anyone is interested.

Sounds like a Condor.
I would think the timing is on a key way shaft on the flywheel. Dont think it would be out.
