Oil is leaking out and soaking foam air cleaner and dripping onto machine, smokes alot when under a load, runs for 15-20 minutes, then quits. what type of oil should be used? how much oil capacity? where can i purchase owners manual. thanks jt in illinois It's not necessarily worn out, because mine is doing the exact same thing (except that it doesn't quit) - and mine is brand new!. Oil leaks out on the right-hand side, dripping onto the "fender". This is associated with a lot of smoking and low power. Then it clears up and runs OK. Perhaps I have overfilled the oil? I had used the machine for a few hours (they filled the oil where I bought it), checked the oil, and thought perhaps it could use a little - only put a small amount in, but that is when this dripping started. Hope someone can help.
