    Queston about honing a cylinder

    I have been told that when I replace the rings on a Lawnboy, I should hone the cylinder to help the rings seat. Can somebody give this self-taught Lawnboy mechanic some instruction on how to do this? What type of hone to use, what type of lubricant to use when honing?

    Looking for a part for 1978 7086 mower

    Here is my solution I've turned it into a Franken-mower. A "fake" commercial mower. I had a commercial gas tank from my scrap pile.

    Looking for a part for 1978 7086 mower

    I am looking for a salvage shroud and gas tank for a 1978 Lawnboy 7086 mower, although there were several models in this timeframe that used the same shroud and tank. I have found a picture from the internet that shows the parts.

    Difficulty backing up..self-propelled LawnBoy F-engine 680546

    Re: Difficulty backing up.I fixed it. Above are 2 photos showing what type of self-propelled transmission I have on my late model "F" engine mower. I rejected the idea that it couldn't be solved, so I took everything apart, and dismantled the tiny multi-plate clutch and washed each blade in...

    When is a LawnBoy truly worn out? I surely don't know.

    So, I have been repairing and refurbishing a lot of LawnBoy mowers, both for my own "collection" (haha) and maybe to sell. Well of course I gave my son a Silver Series 4.5 hp steel deck 10201 rock stock mower to use. It failed on him the other day. It had no compression, piston spun freely...

    Oil seal question 2-stroke Lawnboy

    For a while now I have been using replacement oil seals from Stens. They are black and the outside has a rubbery coating. They work fine. I recently ordered some seals from another vendor and they came in and they are slightly different, they are blue in color and the exterior is hard metal. I'm...

    Question regarding "F" and "V" series engines

    If the newer "V" (Silver series 4.5 hp) engines and the previous "F" engines use the same rings, piston and con rod, how can the "V" series produce 1/2 more horsepower? If all "F" series engines are the same internally, how can some be rated for 4 hp and a few 5 hp?

    Are the rings and piston the same on "F" engine and "V" engine LawnBoy mowers?

    Are the rings and piston the same on "F" engine and "V" engine LawnBoy mowers? Somewhere I read they were, and I want to know. Are the rings, or rings and piston the same on the "F" engine and the "V" engine lawnboys? (silver series) 4.5 hp. I would suspect the con-rod is not.

    Difficulty backing up..self-propelled LawnBoy F-engine 680546

    I have this very nice self-propelled LawnBoy aluminum deck F-engine, Walbro metal carb mower, Model 680546. I have cleaned the wheel gears, both drive "dogs" engage and there is no resistance rolling forward. The self-propelled works fine. The ONLY thing is that there is a lot of resistance...

    Frustrated, trying to get Weedeater to run.

    I've got a few older weedeaters I'm trying to get running, and I am having some difficulty. Take for example, a couple of featherlite models of different vintages. Both have 120lbs compression, as measured via a compression tester replacing the spark-plug, both have good spark, as indicated by...

    What fluid for ultrasonic cleaner for small weed eater carbs??

    Got a small ultrasonic cleaner at Harbor Freight, thought I would use it for cleaning small 2-cycle carb parts such as used on weed eaters. The instructions caution against using solvents and oil based stuff. I was thinking Simple Green diluted with water? Any recommendations?

    Foam for air filters small 2-cycle engines on weed eaters and things?

    Buying specific stock number foam filters for small 2-cycle weed eaters is rather pricey, if one is going to fix them up and sell them. There should be a source of sheet foam for filters that one could just cut down to size with a scissors. Any ideas?

    Threading fuel line into fuel tank on older model Weed Eater

    I have a Poulan Weed Eater brand string trimmer that is almost like the featherlite models, but old enough to only have one fuel line going into fuel tank, and the carb does not have a primer bulb, just choke. Anyway, on "MOST" 2-cycle trimmers the fuel line enters the tank near where the...

    Changing a Lawnboy "C" series engine to "D" series piston and cylinder?

    Changing a Lawnboy "C" series engine to "D" series piston and cylinder? It is my understanding that one can change a "C" series engine to a later "D" series piston and cylinder. From what I have read, one has to also change the connecting rod. My question is, with a "D" series connecting rod...
