I’ve got the idea after some internet research. My buddy donated the lawn mower. It was bought new and had only mowed two lawns and stopped running. I found Burlap wrapped in the blade and the carb clogged. I cost $2.49 for a new spark plug, $2.99 for some carb cleaner, and I had a $10 off coupon from eBay so I bought a throttle cable to rig up for $3 with Coupon discount. I cut off the front of the deck so the blade sticks out about an inch. It cuts down small trees like a knife through butter. I guess I’ll see how long it lasts. I mowed a couple hundred yards of trails the last two days about as wide a truck could drive down no my property. Towards the end of my mowing session it bogged down and killed a couple of times. I’m sure it was because I removed the air filter a few times being it was packed with grass and probably had some dirt or grass Get into the carb. I cleaned the carb and air filter. I also sanded the grey colored build up on my plug afterwards and it started right up. It ran ruff at low idle but when I reved it up it ran smooth. I believe it was from some of the carb spray was wet in the air filter yet after I sprayed it to try and clean. I removed the foam filter and washed it with soap and water. Once it dries I’ll test it again. I’ll grab a new spark plug as well. I’m sure reving it up is hard on the plug as well. Works pretty good. Hopefully it lasts a while. I noticed when I moved the blade back and forth With my hand I could hear some metal on metal...I removed It to re sharpen. Once running I can’t hear any metal grinding. Normal? I figured it might just be just some dust and dirt causing the noise between the shaft and seal. I have huge ant hills I can’t see in the chest high brush I’m cutting till it’s to late and end up running them over. I poured a little oil on the seal where the shaft comes out and it seemed quieter. Well, I already got my money out of it if not and I’ll just keep using it till it stops runnning.
