I got everything back together on the Kohler K341 last weekend and got it fired up. I knew from before that the spark plug hole didn't have the best threads and sure enough when I put it back together this time I didn't like how it tightened up. I should have just redid the spark plug hole with a heli coil from the get go before running it but that is besides the point now LOL.
I used the Bush Hog yesterday to pull the garden trailer and haul firewood from the one corner to our pallets that we have set down to stack it. After I got done with moving most of it I pulled it down to the garage to put air in the tires for the trailer. I have the carb close to proper tune but haven't done the whole thorough tuning yet since it was just put back together I don't want to rev it too high yet.
I had it idling and it started loading up and till I got to it and had a chance to give it a little throttle she backfired and shut off. I just turned the key off and didn't think much of it. Went in to the garage to grab a screwdriver to adjust the mixture screws. Lifted the hood and seen the spark plug hanging from the coil wire. Definitely needs the heli coil done now LOL.
I got the head off yesterday and will be getting the heli coil done this week yet. Would like to be able to use the tractor again next weekend.
