hello all . i dont know much about 2 stroke engines but i have a force 90 (thats all i know about it) im guessing its a merc 90 hp engine 2 stroke. from what ive searched so far on this forum i have found there is no spark in my middle cylinder. took the spark plug wire off the middle while its running and still ran like poo. so i thought it might have been the coil took the middle coil out and switched it with the top and still no spark to the middle. what would be the next thing inline to check?

I had the same problem, turned out to be a bad stator. Check resistance from blue and yellow wires coming from the stator...should be 650-750 ohms.

Re: no spark to middle cylinder

had someone test the stator and they said it was bad. im pretty sure its an 90's model force 90 engine. theres no serial number on it to identify. would this be the one i need? Stator - Mercury/Mariner - 18-5870 Replacement for the 18-5873 & 18-5874 kits
