How overfilling oil caused buddy 125 to stall

[theogonzalez]

I just changed my oil at 8000 miles on my 2018 buddy 125 no different then previous oil changes except I decided not to change the oil filter. It started fine and went about a couple of blocks but then died and won't start. I know that to much oil is bad but the dip stick shows right up on the top and would that keep it from running?. So my question is...Is that to full?
Or should I be trying some other trouble shooting?

How did you check the oil? Dipstick screwed all the way in or dipstick pushed in but not threaded in. If you threaded the dipstick in and the oil level is just over the skinny part that should be ok. If you didn't thread the dipstick in you probably have too much oil.

Running a little bit too much oil shouldn't do anything except lower your top speed. If you are running way too much oil it might cause a problem but I would think it would take more than a few blocks to show up.

To start diagnosing I would start by letting the scooter sit over night to see if it will start the next day. If it starts don't let it more than a few seconds. Then I would also dump some oil out if the scooter is running or not(remove the dipstick and lean the scooter over.) If the scooter runs start it for 2 minutes then shut it off for 2 minutes then check the oil without threading the dipstick in(if you add oil repeat the run for 2 minutes, rest for 2 minutes.) Ideally I like the oil to be up near the fat part of the dipstick put not touching it. If the scooter isn't running I would probably try to start it again(don't try to long though.) If it doesn't start I would start going through the basics, does it have gas, is the spark plug connected, etc. If I don't see anything out of place I would let it sit another day and then try to start it. If it still doesn't start come back and let up know and we can figure out some other stuff to look at.

I'm sure some other people will have some other ideas for you to try.

Stop guessing and do this correctly. Get a clean tupperware or bottom of a gallon water bottle. Drain your oil from the side bolt, next remove the filter screen and drain the remaining small amount. If you are leaving your filter inplace, the scooter takes 25.5 ounces. Next measure 25.5 oz from the jug and refill the crankcase. Did it solve your problem? Maybe, maybe not, but you have ruled this out as the culprit.

I don't understand the sitting/starting/stopping/dumping test.

I don't understand the sitting/starting/stopping/dumping test.

The only test is seeing if the scooter will run after sitting over night. If the scooter starts I would want to get the oil level right so I don't risk having the scooter die and not start again. Even if the oil level isn't the problem I would want the oil level to be correct so that would be eliminated as a cause of the scooter dying and not starting. If the scooter doesn't start after sitting over night then I would try some other stuff, but I will wait to see if the OP was able to get the scooter started after letting it sit before I make those suggestions.

Since there is too much oil the OP will need to dump some out(or dump it all out and refill.) Once you dump some oil out you would need to check the oil level and the way Genuine recommends checking the oil level is by running the engine 2-3 minutes then letting it sit 2-3 minutes before checking the oil level*. Every time you add or remove oil you would need to repeat the run the engine for 2-3 minute, rest for 2-3 minutes, before checking the oil.

Hopefully that makes a little more sense.

It makes no sense. Eliminate any issues with the oil level and move along.
