    Compression issue after rebuild

    After you take some time away from your engine, disassemble it and re-assemble, but take an extra look at the carburetor. I'm speculating that you may have assembled something incorrectly and/or the fuel system isn't cooperating.

    Used mower - high oil levels

    Total, spontaneous remissions of every sort of cancer occur frequently enough that cures like de-wormer, krebiozen, or sitting in a uranium mine can gain credibility. None work. If you have credible evidence that any physician or medical center is engaging in dishonest practices, kindly...

    Is the Lawn Boy 5024 blade collar threaded?

    I finally removed the blade collar by drilling a pair of holes in it, bolting the thing to my heavy-duty puller, and using such brute strength as I can summon up at my advanced age. By this point the blade collar was about as bunged up as one could imagine, so I reinforced it with a piece of...

    Is the Lawn Boy 5024 blade collar threaded?

    My mower is the two-stroke non-self-propelled 'brick top' Lawn Boy, or Lawn Bo because the 'y' got obliterated by gasoline. The photograph was posted by someone else. The blade shaft pokes out of a fairly long snout at the bottom of the engine, and the bottom seal is a few inches inside said...

    Will not start after engine is hot

    The traditional problem in a Briggs and Stratton engine that won't start when hot is that the valves are out of adjustment. As the engine wears the valves sit lower in their seats and they'll leak slightly when the engine is hot because the valve stems expand with heat. An engine so encumbered...

    Is the Lawn Boy 5024 blade collar threaded?

    Thanks. I should be able to rebuild the collar if I can't find a new one. This mower is from 1975, and I did not post a photograph. My guess is that there's a lower plate that I can unbolt to get at the seal, for I cannot think of a seal puller that would pull a seal from a hole several...

    Lower seal 5024?

    l've finally removed the blade collar on this 5024 rotary mower, but the lower seal is several inches down a hole. Does the engine have to come apart to get to and replace the seal? Thanks. Mark Kinsler and the grass is slowly obliterating our house...

    Is the Lawn Boy 5024 blade collar threaded?

    Thank you. After much labor, It's off, albeit in poor condition. How do you get to the bottom seal?

    Is the Lawn Boy 5024 blade collar threaded?

    Well, that didn't work. Reseating the top seal didn't do a thing, and the mower only runs on the ether starting fluid I'm able to squirt into its air intake. I think I'm out of ideas, but I like this mower a lot. Clearly it's not getting fuel. Some facts: The entire governor and spark...

    Is the Lawn Boy 5024 blade collar threaded?

    Thanks. I was afraid for what I assume is a delicate magnesium mower deck. It wasn't clear how the long pipe and hammer was supposed to work, for it looked like Mr BogdaN was trying to unscrew it. In any event, nothing worked, including a three-jaw puller that merely served to bend the...

    Is the Lawn Boy 5024 blade collar threaded?

    Thank you. The mower would run only intermittently, and I suspected an air leak. After elaborately sealing the carburetor I thought I'd look at the crankshaft seals. Behold, the top one had blown out completely, but the bottom one remains inaccessible. If I can get the blade flange un-bent I...

    Is the Lawn Boy 5024 blade collar threaded?

    I could not figure out from the other posts whether my jammed-on Lawn-Boy 5024 blade collar is threaded onto the engine shaft or is pressed on. Some say to use a puller to remove it and other show it being tapped off as if threaded on. I had no luck with a puller and heat. All I want to do is...
