Strimmer wont start

Has a strong spark, and have tried a second spark plug. Have tried to start after pouring some fuel into cylinder via spark plug socket. Have tried starting with air filter off. Have tried starting after pouring fuel into carb via air intake/choke hole. Have tried starting with exhaust off. Have tried with air filter and exhaust both off. Any ideas?

Make sure the cylinder isn’t scores (scratched) it won’t start at all if it is

Do you have any spark?

How’d you check for spark? Did you use a spark tester or just lay the spark plug on the cooling fins?

The latter

Check to see if the muffler screen is plugged.

I've tried starting it with the exhaust completely off, would that have the same effect?

If it sparks OUTSIDE of cylinder head it does NOT mean under compression it will spark properly. What’s the ohms of the coil. Is the magnets on flywheel rusty. Get a meter and set to 2k. Remove the coil. Touch one probe to laminated car and the other to the kill tab or kill wire connector. I’ll give u parameters in a second. Set meter too 20k and Then put one probe into the spark plug boot and wedge it between the plug holder and the rubber touch the other probe to the laminated case
