Re: 1993 2-stroke Yamaha - gear oil through weep holes?
First, thank you for all your support and help!
On Friday, I received the remaining seals and gaskets necessary to rebuild the lower drive uint. Although I was somewhat trepedatious when I set the engine on a saw horse and lowered it into a garbage can of water, I was pretty confident that the gear lube leak was fixed. When I finally took the entire unit apart - yes, every piece and seal - several seals had been dessicated over time and others were actually ripped! The worst offenders, no surprise here, were related to sealing water from oil.
So, When running the engine, no problems with the leaking gear lube! I was very happy. But...
The engine stalled easily and ran rough. So, I removed the carburator and took it apart. Clean as a whistle! Not what I had hoped for. But, I also took off the gas filter and found water mixed with gas plus a few bugs. Cleaned and replaced everything and then set the gap on the spark plugs - again to be sure.
The engine is now running like a charm!
