    More problems on the 425 Kohler CH25

    Well…no joy. I started it again a little bit later after adding more fresh gas. It started so quick—almost the moment I turned the key! But I shut it off quickly, because I meant to check the oil. (I had just changed the oil with the good stuff before I tore it down. But wanted to check anyway.)...

    More problems on the 425 Kohler CH25

    UPDATE: March 27, 2024 FINALLY! Back together today and nervously gave it a crank. New tank of gas, some Choke, cranked about 5 seconds and Voila! Fired right up. It seems to be “jumping” a little at this low speed. Ran it about a minute and shut it down. During that run period I thought I...

    Replace motor on MTD 5hp chipper shredder—shaft?

    Odd, but I’ve replaced carbs on a couple of lawn mowers, small tractor, and chainsaw with cheapies and so far so good. But yes, I believe it would be better with OEM parts. But EXPENSIVE. When I can, I’ll get the good stuff. For example, I’m having to do a lot of top end work on a finicky Kohler...

    Looking at more documentation, I can’t see where the “jug” separates from the block…am I missing it?

    More problems on the 425 Kohler CH25

    When I first saw it, I had been considering…(keep in mind I have no real “skill” but have always relied on trial-and-effort, printed materials, and plain old ‘I think it works like this—what if I try this?’”😆) …that since that depression opened up that space just a little more that it would be...

    More problems on the 425 Kohler CH25

    Oops—my fault! I didn’t think it through enough, and when you mentioned “jug” I remember that from a small Honda cycle motor I was working on a couple years ago… So that “jug” separates from the block as well, enabling it to be replaced? I think I need to study a little more—I thought I had it...

    Replace motor on MTD 5hp chipper shredder—shaft?

    After more consideration I’m going to leave it alone—go back to the original motor. Got a new carb ordered for it and that should get it back up to snuff. Thanks for the help and interest. 😊

    Replace motor on MTD 5hp chipper shredder—shaft?

    I mistakenly ID’d my motor as a Predator—after a better look I find it’s a “Starter USA Professional” model. (Must have been before Predators) …and another label says it’s a “gosoline” engine! 😜 It’s shaft mics out at .62 mm or 5/8”. The original MTD final shaft end mics at .87 or 7/8”. 😯

    More problems on the 425 Kohler CH25

    LOL I probably didn’t detail it correctly—the impression is in the block part. I think the heads are ok after a little prep work, and all new parts to boot…but… Now…I’ve come to the point of it being apart so long I kinda dread starting back on it. (Seems to have gotten worse with age😯) I have...

    Replace motor on MTD 5hp chipper shredder—shaft?

    Hmmmm…I held a tape measure under the shaft and tried to line up with both sides of the shaft to come up with the 5/8”…I’ll put a micrometer on it shortly and see what I get for sure…

    More problems on the 425 Kohler CH25

    I hear you! 😊 It sure alarms me too, but I haven’t gotten back to it this evening (had to make long distance run with wife for groceries and meds, and it’s been pouring the rain…arrrrggggg) Also, it appeared to me that the surface area of the impression is smooth—I would have thought it would...
