Excessive oil in top end?
Posted: Sat Sep 10, 2016 11:12 am
Thanks in advance for sharing your knowledge of these little Sprees.
A little background on mine: I got it not-running from an Estate-the owners son told me it needed a coil and had no spark. Well, it
had spark, but was getting no fuel. Since it had been stored for years with fuel in the tank, I tore apart and cleaned the carb the tank was very clean inside. It wasnt gunked up like you would expect, but
there was an oily substance thru-out. After putting it back together, I started on the lack-of-fuel problem. Even sucking on the vacuum side of the petcock produced no flow,
so I let it sit with Berrymans in the inlet side a few days. Encouragingly it came back to life and fuel filled the carb. Now, just to make sure I wasnt wasting my time, I primed the cylinder with a tiny bit of gas, and it fired right up. Cranking it with the starter didnt have the same result so I checked the plug. It was wet with oil(not gas and oil-just oil)
I burned off the oil with a tiny butane torch from Harbor Freight

and primed again thru the spark plug hole. Same result-ran a few seconds and died-same oily plug.
I dont have a compression tester that fit in that tiny space, so I put my finger over the hole and cranked it a few seconds-there's compression and my finger was extremely oily.
This looks like maybe 2-stroke oil-possibly from the injection pump? but the hose from the pump is empty( I dis-connected it to make sure that wasnt the source.)
Removed muffler-only the usual amount of 2-stroke combustion inside(I hung it so it would drain any oil-nothing came out overnight)
Short of hanging the scooter upside-down to drain it, You guys got any ideas how to remove the oil in the cylinder?
I have sprayed carb cleaner in the exhaust port and spark plug hole, and cranked it over, but that doesn't seem to make any difference in reducing the oil amount.
Possible clue? I checked the level in the 'transmission' case-behind the belt, found it was low(I couldnt tell HOW low)
Is it possible that's the source thru a leaky seal?
2500 miles on the Spree-engine looks like its never been apart.
Sorry for the l o n g post-Im trying to bypass all the questions: "Did you try this..."?
