Would you like me to blow up a chinese MTD for you joe???

I have one here thats got a real bad rod knock.
I had a flymo with a 375 sprint on it that was a bit sick the other day, i did contemplate letting it lunch itself. It ran real nice untill you loaded it right up nearly back to idle speed then it would chug blue smoke for ages and eventually get its revs back and clear the smoke after more than 30 seconds. Bore was all scored up.
