    What is the reason none of the String trimmers, hedge trimmers and blowers have engine that has cast iron lining? Even the best of the best have only chrome plating except Maruyama who claimed it is chrome impregnated. What is even chrome impregnated?:waving:

    I had thought it was to keep the weight down. Sorry, I don't know the difference, if any, between chrome plated and chrome impregnated. But if I had to guess, it would be that impregnated would mean more chrome.

    There is a lot of heat generated in high rpm 2 strokers. Aluminum transfers heat much better and quicker than steel.
