GT2544 spitting, sputtering, smoking and erratic idling - Oh my!
I have a GT2544 that was idling pretty rough a while back, so much to the point to where it just kind of "crept" around the yard idling super low (even though throttle was on high). I took it to a guy who did a standard tune-up on it, cleaned the carb, etc and when I got it back it ran like a champ.
About a month later it started exhibiting the exact same issues, but now it is way worse. Essentially when I crank the mower it runs great, but when I drive it any distance (100ft or so), especially with the PTO engaged, the motor just bogs down very low and sputters with black and sometimes white smoke, and it barely moves. If I leave it sitting idling sometimes it will begin idling properly again, and again I take off around the yard only for it to bog back down again (sometimes after making it all the way around my 1/2 acre lot, other times within 50ft or less). 2 weeks ago I'd left it sitting for a day, and came out here and there and made a lap around the yard before it would quit each time. All the sudden it decided to keep on going and I cut for 30 minutes with no issues... go figure. It's also drinking gas compared to normal.
I know this is going to sound crazy, but today I pulled the left plug boot, it zapped me and the engine died immediately. When I pulled the right one, it kept on going just like normal, and I could not see any spark and I didn't get shocked. However, tonight the exact opposite happened. It was running rough, and I pulled off the right plug boot and it died. When pulling the left one, it kept running fine. I'd just put in brand new plugs at the time.
Some things I've read lead me to believe that it may be a bad coil, but I'm not sure, and I have no clue how to get the top of the motor off to replace it.
I'm about to give up on this thing it's running me nuts, please help!
