I haven't worked on small engines in years so I need a memory refresher...can't be that I'm getting old....
I have a 35t log splitter with a B&S 15.5 (whatever THAT means now! Ft Lbs?) engine. I did have to do some "reconstructive" work on it after my son forgot that you need to slow down for turns when you have a high center of gravity & a narrow wheel base but it didn't appear to affect the engine and I've used the splitter for several hours since. The biggest thing was replacing the broken fitting from the hydraulic valve to the cylinder.
It's been getting harder to pull since then. It used to spin right over (hand pull) but it almost broke a bone in my hand yesterday when it kicked back and the pull handle nailed me! Got a *nice* bruise and I normally don't bruise.
Any suggestions on a probable cause for becoming hard to pull? I haven't started taking parts off but I'm wondering if the flywheel key is partially sheared and it's thrown the timing just enough to cause the problem.
It still runs fine but I have noticed a slight difference in the engine tone - like the choke is still partially engaged. I've checked. It isn't.
I hate to just open equipment up without having an idea of what I'm looking for. We did that on routine inspection on turbines but this is on my dime and I don't want to take apart more than I need to!
