Excessive oil in top end?

[patthesoundguy]

This is a sort of common spree issue. Over long periods of time you get seepage from the oil tank through the pump filling the bottom of the crank case with oil. Pull the motor out of the frame, pull the top end and turn it upside down to drain it. You may not need to ditch the pump it may work just fine it may have just seeped oil when it was sitting at one point. The pumps usually work fine it when they sit for long periods sometimes they can seep some. Don't ruin a perfectly good pump grinding the teeth off until you are 100% sure its toast.

Buy a oil plug dont grind your pump someone will buy it. Also a oil plug will increase crank case pressure, when you geind the teeth off you lose a lot of pressure then if you get it to hot while your grinding on it, it can cause the shaft to warp.

OK, it's back among the living! I pulled the pipe/muffler and hung the scoot by the rear wheel.
Sprayed carb cleaner in spark plug hole and cranked it with the starter(many times-someone on here suggested
3-second bursts in order to not burn up the starter. That flushed out the oil enough so I could get it started(on pre-mix)
I also BBQ'd the muffler while it was off. The first time it fired the neighbors thought the garage was on fire from all the oil burn-off
After that cleared I ran it down the block and it got up to an indicated 28 mph, so I'm happy.
After a few laps the oil pump started doing its thing, so I'll drain the pre-mix and run it as Honda-san intended.
Thanks, you guys, for the suggestions, and for this Forum. btw I bought a filter and a plug to give a tiny bit of pay-back.

Right on!

A new issue: The bolt that holds the oil pump to the engine is tight, but there is some movement.
I can wiggle the pump a bit. Your thoughts?

missing oring on the oilpump

Best guess is it slowly seeped from the pump reservoir down into the engine. That's what makes the most sense anyway.

This. I've personally seen this on stored bike. Slight leak in oil pump completely filled bottom end. I stupidly put engine back together like this thinking it would burn off.

I ended up removing the engine and jug and inverting it to drain most of oil, leaving it overnight. That fixed issue after it had run a bit.

OK thats probably why it's a little 'wet' in the area. Good clue.

Thanks, to both of you for the explanation of where the oil came from

Do you guys think it is necessary to remove the top end couldn't you just remove the oil pump and flush the bottom end with pre mixed fuel and just dump it right back out the oil pump hole ?

[Ultraliner]

Agreed wwolvert, i used that exact method when i first got my scoot that had suffered the exact same problem. Just stood it up on its nose while holding the front brake on to drain the oily 2 stroke out of the crankcase through the oil pump hole. Pretty messy but quicker than pulling the motor

My Spree had the same issue, but mine was so full of oil from sitting that you could kick it once and it would hydro lock. It had been sitting with fluids in it for about 5 years. All I did was pull the spark plug out, stuffed a rag over the spark plug hole, then gently pushed down on the Kickstarter. Then I used the electric starter, cranked it over for about 10 seconds (No compression so there's not much of a load on the starter) Did that 2 or 3 times, let the starter cool for at least 2 minutes each time, then hosed down the block with carb cleaner to get the oil that dripped and didn't get soaked up by the rag. Carb cleaned the spark plug, stuck it in, cranked it over, kicked a while, cranked again and it came to life.
