Kawasaki V Twin vertical shaft sensitive to inclines ?

So yesterday I was mowing and a neighbor walked up as I was pointing uphill maybe 10-15 degrees. I idled a bit and shut it down. About 20 minutes later I started it and the oil smoke was crazy bad, billowing eye burning smoke. I thought maybe 6 1/2 hours was all I was getting but it started to clean up so I mowed and all seems good to go.
Cylinders face the rear so is it that the rings are not seated or????
To service the deck you lift the front up, how is that supposed to work....
Dump oil, check blades and refill??
Thoughts anyone?

 

Is it possible its overfilled just enough to cause that? I have a steeper incline than 15 in our back yard that I park it on to wash the deck off as it runs off faster. I also use a hoist to lift my ZT up to remove the blades. I haven't had any smoking issues. Mines a kohler V-Twin but the orientation is the same.

 

Carb float was probably in a position that allowed a little fuel by...ran some down the cylinder walls.
Whenever I shut mine off I close the fuel valve, it acts a little flooded/smokes if I don't.
Also Kohler v-twin

 

I thought he said oil smoke. My bad. Lol

 

Carb flooding/float leaking can wash down cylinder walls, makes em smoke blue like crazy!
And if it's really bad, and it leaks enough that the fuel dilutes the oil, that can make the engine smoke full time (as in, doesn't just clean up after a minute or two)

 

Now that you mention it, I had a Murray with a big opposed briggs twin that had a needle/seat leak and it smoked blue like crazy if it sat overnight. I forgot about that. If sat longer it would start filling up the crankcase. I cleaned the junk from the carb and it stopped. That was quite a while ago.

 

When I was still at the bike shop we pretty regularly would drain "oil" that was 2-3 qts of oil/2-3 qts gasoline...mainly on ATVs and bikes that had gravity feed and a manual fuel shutoff (models with Mikuni carbs tended to be the worst offenders)
We always recommended to customers to shut the fuel off as soon as the engine was shut off, but most models were ok for short term if you didn't...the thing that sometimes got the guys that "never" shut their fuel off was when hauling the bike with fuel left on...bouncing down the road and the float needle was just going "squirt, squirt, squirt"

 

My dad had this happen to him recently on his rototiller. Said he went to start it and it was real hard to pull over. He then checked the oil and when he got the cap off it came out like a geyser.

 

Good thing he wasn’t ripping a dart!

 

There’s some low hanging fruit there..
but agreed, I’ve experienced the same, many times over. And yes, I mean about the bike shop experience.

 

It was definitely oil, no scent of fuel at all.

 

This was not a bit of wash. Doesn't the fuel shut off solenoid take care of carb dribbling?

 

Not overfilled, right on the line and the level hasn't changed up or down.
No fuel in the oil either.

 

Depends, if it is a fuel shutoff solenoid for the bowl (not common) or a main jet shutoff to stop/limit backfiring after a hot/full throttle shutdown...if it is the latter then no, fuel to the bowl/float is still "on" even when the key is off (assuming gravity fuel deliver, which even though many of these engines have a fuel pump, needed or not, fuel seems to be able to gravity feed past the fuel pump, to some degree anyways, it does on mine, and I have one at work that's the same way too)

 

I get this every once in a great while on my Simplicity riding mower. It has a Briggs V2. Never found a specific time or situation to pinpoint a cause. I rarely park it on a slope but when I do, it’s usually to wash the deck etc, and I’ve never noticed it do it then.

 

I believe that it shuts the jet.
