They vibrate a bit. Its kind of an F engine and kind of not. Most people pass or trash them, but had one for years and didn't have any trouble other then needing a primer bulb. Always started so, my opinion is its not a bad engine.
Started working on this one. The PO had used zip ties on the FW brake bracket because the cable had seized. Not sure how he was killing it. Anyway I got the cable freed up and the FW brake bail is working properly.
Then checked the gas and there was water in the gas tank from being left outside. Cleaned that out real well and figured I'd just try it even though it doesn't have a primer bulb. No dice of course. Then I tried just blowing in the primer line and I got it to kick off for a couple seconds so I figured there was no getting around having to remove the carb and clean it.
So now I've got a perfectly clean carb, of course it has water in it too, cleaned out gas tank, still no primer but you'd think if I can just get it to kick off again that a clean carb would allow it to run. Well it runs for a few seconds and dies every time now. I can even wait a little bit and start it without priming and it does the same thing. Seems like fueling to me but I only had limited time to mess with it this morning so I'll dive into it more tonight.
Got the primer bulb tonight, at first you have to keep it running with the primer but then it runs decently when warm. Sharpened the blade over the weekend, mows ok I guess. It's just a mower, doesn't seem very special like the older ones. Maybe that's just me. I'll keep it around for now though.
