Hello everyone. I'm new to this forum and I'm sorry to say that I come bearing no gifts, just needs.
In the middle of mowing my Tiger Cat(STC532V-691FX) started running rough, almost sputtering. It didn't matter if I had the blades on or off. If I pushed both control arms forward at once, the rpm would die down. I figured out that one side wasn't getting spark, so I replaced both ignition coils, air filter, and spark plugs. Then I realized it was running only on the number 2 cylinder.
After putting the thing back together, the engine won't start if I tighten the bolts holding the engine cover. If I loosen them, the engine will start, but will continue to run rough as before. I just checked, and once again, one side is not getting spark.
I removed the number 1 valve cover and regapped the valves. I sanded the coil posts. The mower starts and immediately dies if I pull the kill wire off the coil.
Does anyone have any ideas?
