    Identifying an old Lawn Boy mower

    Hello, I have had 3 different mowers with decks just like yours except not so dark green. I am guessing that yours is early eighties. A pre compliant mower, blade control handle I think they made the f-100's from 1978 to 1982. Then they started putting metal walbro carbs on a lot of F engines...

    Duraforce carbs

    I have worked on several duraforce mowers and I have a problem with the air vanes sticking and the mower revving too fast. The air vane works free until I tighten the two bolts that hold the carb on and that seems to put the air vane shaft in a bind and it won't spring back. This has happened on...

    Lawn Boy 10552 Where Does Primer Line Attach

    Hello, The primer hose connects to the top right side of the carb if you are standing at the back of the mower. The little tube inlet goes straight up and down vertically. It is just inboard of the gas line tube connection that is horizontal. So if you get down mower level and look at where the...

    How to check the kill or shorting switch on a D600

    Switch was bad. Swapped it out with another switch from a running mower and it took right off. A new kill switch is on its way. It helps to have extra mowers setting around. Jerry

    S21ZSNA, 680530

    It is good to see someone else interested in the old 2 strokes. A lot of people either love lawn boys or they hate them. I know several people that needed a push mower and I offered to give them a lawn boy and they were not interested because they had to mix the oil and the gas. I believe your...

    Lawn Boy F100 and F model

    I have an extra engine (short block) from a 1987 steel deck that rusted out. I honed it out and put new rings in it and just let it set for 3 or 4 years. I just put all the other engine parts from the 7229 (1979) together and am hoping it will run ok. The only thing I need is an exhaust gasket...

    S21ZSNA, 680530

    I think if they are in good shape and do run good $150 is not a bad price. If I remember right these two mowers are almost like twins. They both have F engines and self-propelled. I enjoy keeping older Lawn Boys going. Parts are getting more expensive and a little harder to find but there are...

    How to check the kill or shorting switch on a D600

    I am trying to get a IH model 3311 from about 1973 to run. It has Lawn Boy D600 engine. Everything looks good. Coil checks out, spark plug is sparking, it is getting gas. Cleaned carb, kill switch is connected, took flywheel off and governor system looks in order. I am going to take the blade...

    Lawn Boy F100 and F model

    Well I think I answered my question myself. The short block or the basic part of the engines look to be the same. I think the differences seem to be the shut off system, or kill switch and the brake stop, and the throttle controls. Things were a lot simpler before before the government rule...

    Lawn Boy F100 and F model

    Does anyone know the difference between the 78 to 82 F100 engines and the later 80's F engines besides the type of carbs they use? The F100's do take a different coil than the newer F models. A friend brought me a model 7229 to work on and said it wouldn't start. It was getting spark and gas. It...

    Lawnboy 10525 9902098 Recoil

    Hello, I looked up your model on the toro master parts list web page and it says the recoil assembly is part no. 99-6713. They are all discontinued. I needed one last year and couldn't find one. Then one appeared on ebay 2 or 3 months later. There might be superceeded numbers that are different...

    Law boy 10328 Self Propelled Duraforce--Muffler

    Welcome to the forum. Yes I think you need that U pipe for the exhaust to go out the muffler up top. The exhaust goes out the bottom of the engine through the exhaust ports and goes down and then back up through the deck into the muffler. I have had that plate off of several duraforce mowers...
