My day started yesterday with a customer bringing his 2 week old DR trimmer with no oil showing on the dip stick,no resistance to the flywheel turning, and the customer complain that it just shut off, and then it wouldn't crank over. About 6 ounces of the required 16 ounces of oil found in the crankcase, and pieces of broken rod. Slight aluminum transfer to the crankshaft, with mild scuff marks on the cylinder walls. The other odd thing is with less than 5 hours of run time the crosshatch on the cylinder walls is gone with no evidence of dirt intrusion. the oil looked like it had been drained from a old gearbox.
