I got weak spark so wont start got new plug

it means it is a weak spark, are they he correct plugs with the correct gap

no such thing as weak spark on a 2 cycle engine. it either has it or it don't. wont start on starting fluid means other issues like crankshaft seals, or plugged exhaust or no spark

pull flywheel and replace sheer key on flywheel to get spark on time

Sounds like stator pick up or stator its self is rusty causing a weak spark, (Just sand off) , or the coil is bad or spark plug wire is corroded

first check your compression....if weak...could be a few things to look for...valves not closing...timing...

If you have tried a new spark plug, and diss connected the earth cut out wire from the back of the switch ( to rule out a switch problem ) then it is going to require a new ignition unit.

check pulse generator circuit for any opens or shorts..even if you still show a weak purplish/red spark its bad..it must be a big bluish/white spark..check plug #1 for spark and then check #3 foe spark if there both week then its your pulse generators that are bad ..but if one of them has a blushish spark then it that systems coil..eg #1and#4 or the #2and #3 coils..

try a new spark plug, if the sparks plugs really black its probably fowled so wont work. That should fix your problem, if not pm me

The engine case needs to be removed to expose the flywheel and ignition module. Check the module pole gap to the flywheel magnets with a thin business card for a gauge. If the gap is excessive, that can give a weak spark. If the gap appears to be correct, then it is probably time for a new ignition module. Make sure the spark plug is gapped at 0.020" before condemning the module. The spark should be blue and snappy. Check it in a dark area. Hope this helps!

You should check your leads. if they are silicone a slight bend can break them and you will have a very weak spark. Also check the gap on the spark plugs, if the gap is too small there wont be a very good spark. If those are all ok check the coil pack(s), they may need replacing.
