Eng wont start, plug chngd, gas check good - Poulan/Weed Eater #Wt200 711724 24cc Gas Blower/Vac

so sounds like you need either 1 or more ignition coils replaced,have it scanned to see which cylinder/cylinders it is,plugs should be replaced as well because of carbon tracks on the plugs...this will ruin new coils!

check for spark at plug if spark at plug then squirt some starting starting fluid in carb see if will start it should run long enough to burn out starting fluid if does check for water in gas if is drain tank and carb bowl put in fresh gas not and repeat not old gas you were using strat lawn mower if still dosnt start rebuild carb and add and additive called seafoam to the gas this is good stuff follow instrution on bottle

The battery voltage on a Suzuki I had would drop low enough during cranking with the electric starter motor not allowing the spark to be strong enough to run, the voltage regulator also didn't function correctly once and as the battery voltage dropped during operation engine would start to bog down and cut out due to low voltage for the ignition system.

Has gas where--- in the fuel tank?

Put a fuel pressure gauge on the
fuel rail & see if you have a working
fuel pump,system & pressure,somewhere
around 40# with key on/eng off

I assume the engine turns with the starter

Is the battery any good,start there,can read 12.5 volts
& still be bad

Will it try & start if you spray the throttle body with starting
fluid or carb cleaner

If you have spark plug wires, put an old plug into one wire
& ground it on motor to check for spark

You can have spark but too weak to run motor

Make sure all fuses are in place & good

the primer bulbs do tear also if the passage is plugged it will not prime

check your oil is it up to full, then I would check to see if you have compresson, pull your plug and roll over and feel with finger ,but don't touch spark plug wire or you will light up! next I would check for spark, then for fuel, make sure the carb is getting fuel,,,check your hoses and fuel cap and clean your carb and needle/seat and make sure gas will run through the fuel line. Also you could have sheared a flywheel key

the choke out you are talking about could of been a lean condition and smoked the eng rings
Good Luck compresson test should tell all 2StrokeJim

If you want to check to see if you are getting spark - remove a spark plug and reconnect the plug wire. Be sure the plug is grounded to a good ground on the engine and try to start the eng. If there is spark seen at the electrode of the spark plug then it is not your ignition system (as far as spark goes) If you do not see spark it could be your coil or possible your ignition module (in distributor) I'm guessing you have an ignition mod - you do not mention the eng you have.

very poss it could be crank sensor ,broken wire ? timing belt? advise installing scan tool that reads live data check eng rpm on scan tool see if shows eng rpm while cranking , poss remove upper timing belt cover make sure is turning and not damaged, poss computer related problem or power to eng systems would have to check for power at fuel injs and check for ground pulse with logic probe or led test light if crank sensor ok also check for spark at plugs with special plug tester and check codes first

check to see if gas is flowing from gas line make sure fuel tap is turned on. Check the plug and replace it if not new check to see if the carburetor is dirty. Make sure if you have an oil injector to check the oil lines. To name a few things.
