What would cause no spark? the mower is a masport 8/02 two stroke. Will not start and I have changed spark plug and cleaned every thing but still nothing.

Your spark plug wire may be damaged, or your magneto may be too weak to generate a spark. You also have a kill switch wired to your magneto, and a condensor. I would start by cleaning the contacts of the magneto and then check the gap between the magneto and the flywheel. The gap between the flywheel and magneto should be .010". I would start by checking the kill switch wire for damage. If any damage is suspected, replace the kill switch. Next, I would have the magneto tested or replaced. Also, check all your ground wires for damage, or loose contacts.

When you are checking for a spark, you should have the spark plug installed in the spark plug wire as normal, but not installed in the engine. The spark plug base should be grounded to the engine while trying to start and checking for a spark. If there is a weak spark, this is probably due to a worn magneto.

My masport genius xrs will not start seems to be electrical, cannot see a spark with plug out of engine and connected.

hi if the xrs engine is briggs and stratton

try new plug 1st , then pull the kill wire from the stop switch and retest for spark

if still no spark take top starter cover assy off the mower and pull the kill wire off at the armature
temporarily fit the starter cover and retest for spark - if still no spark the faulty armature indicated
replace the armature - and set the air gap between armature and flywheel ( with magnets under it )to 0.010" and tighten the bolt - refit kill wire to armature and stop switch and refit starter cover assy and plug - should all be good

NOTE to obatain correct armature for engine make a note of numbers off the starter cover
eg 12f802-01215-e1 give the numbers off your starter cover to your local smal engine shop he will be able to get new armature for you .

cheers hope it helps
