Motor rebuild --Help--

Ok guys, question for the engine rebuilders.

Thinking about buying a Scag 48 Hydro with a 15 Kaw on it. Spoke with the owner and he tells me that the engine burns about 20% per 8 hrs run time. Trying to evaluate if i can save the engine or just replace it.

I am mechanically knowledgable and have worked on plenty of 2 cycles and 4 cycles. I'm guessing the rings may be worn, scored pistons/walls.

What do you all think that could be causing that much oil to burn? A new engine in 1050 so if i can tear it down and get it running smooth for around 400 max i would go that route. Let me know your thoughts.

Thx

Is it leaking oil..or burning oil...or both..???
Its impossible to know what's wrong with your engine without a teardown and close inspection of the parts..
Rebuilding an engine properly takes more than ability...it takes the proper tools and the experience to know how to use them..
Being familiar with what is normal wear ..and what is damaged will make all the difference in your finished product..
Engines aren't cheap...but neither are the proper tools to rebuild one...though the most expensive thing I've seen on rebuilt engines...
Is the lack of experience....

Hey Greyst just get a new engine. OK now if you want to get a set of oil rings and set of reeds go ahead have some fun. A full rebuilt in my opinion is a negative.

Oil rings are not available separately....rings are only sold in sets..
This engine has only 1 reed valve...not a set of them..
IMO..with your knowledge ...a new engine would be the smart move...

Greyst....if you have the tools..and feel comfortable rebuilding an engine...go ahead...
If its just rings...gaskets...and seals..and tuneup parts....should be less than $200...
