OK what is it with K241's in the last 2 weeks. Mine, then yours. Please check my previous post. I did the same thing and nothing, ran like crap. What I found was a bad condenser wire at the coil,was making a connection about 99% of the time. I put on an old condenser from my junk box and it runs great. I cut about 1/2 acre and it quit. Found the coil almost to hot to touch. It started up but ran real bad, made it back to the shop and put a fan blowing on the coil to cool it down. When the coil cooled down I was able to cut for another 30 minutes (got dark had to stop) without any issues. I will change the coil and condenser. Hope this helps.

Backfiring??? Firing a little to soon. Check your point gap, get it close then put a timing light on it to insure it is dead on. When was the last time you set the valves? Intake valve may not be fully seated when it fires. If it isn't seated, this would explain backfiring through the carb.
