Here in NY it's easy, all the service and auto parts stores have to take it free. This includes Home Depot and Lowes since they sell oil. Metal oil filters need a hole punched in them to drain excess oil and then are disposed of. Two shops by me have waste oil heaters and use them to keep the...

I went through this with my neighbors Craftsman Lawn Tractor. It was not easy. Tried all the methods here. Heating, cooling, penetrating oil, gear puller, hammer & chisel, etc. I did not want to pound too hard on the rim from behind as I worried about the transmission. I went to a friends...

Could you do a compression test? What do the spark plugs look like?

I figured it was time for a mid July update. The mower was initially running well. A couple of weeks ago it developed a small backfire. It got progressively worse, and the right cylinder was not firing well. I decided to give it a going over and checked and reset all the valve and coil...

Lets just say oil has additives and call a truce ☮️. The old Xerox- Copy argument. Detergent is a generic name. From the Interweb "Engine oil always has additives added to its base stock. Base stock or base oil is the primary component of engine oil resulting from petroleum or chemical...

Interesting discussion. One issue with using my picture though, as I mentioned earlier I added BG EPR® Engine Performance Restoration® to the oil, and put Wurth Engine Cleaner/Conditioner through the intake. These 2 products removed quite a bit of the build up inside the engine and combustion...

I finally had a bit of warm weather last week and gave the mower a break in run. After a nice run I drained the oil. It was of course quite dirty from assembly lube and ring seating. I gave it fresh oil and this week used it for an hour with the trailer hauling debris from my spring yard...

I finally finished using the mower for the season, so it was time for a tear-down. I removed the majority of gunk from the engine, with a little further clean up to go. Before I pulled it, I added BG engine cleaner to the oil and some Wurth intake cleaner through the carburetor throats. Prior...

It may be that the plug was worn and the gap was no longer correct. Can't really tell much without the plug. Will it run better the more you use it? Maybe. If a bit of carbon built up with the fouled plug, it may clear up as you run it and the carbon burns off. If it fouled due to a...

I'm sure there is carbon buildup, which is why I think it is time for new rings. I use Rotella 30wt.

Is the plug fouled from running rich, or oil fouled? If you can, post a photo of the plugs. I have a Craftsman Lawn Tractor 21 Hp, 42" Mower Model No. 917.271851. Mine currently had an issue with a fouled plug from burning oil. I will be taking it apart this winter to see what shape the...

I have a 19 year old Craftsman 42" Lawn Tractor with a Briggs & Stratton Model 407777 Type 0167E1 Code 020311YG engine. It has done well over the years, but oil usage tells me it's time to open it up. I'm thinking it will need at least a new set of rings, but of course I won't know for sure...
