Thanks Chris. I just thought it best to check. They do seem like pretty strong engines.

On a seperate note I dont suppose anyone would know how to get a blade guard for a full crank utility mower that I found at the recycle place. I only spent a couple of bucks on it and it runs like a dream however I dont want to sell it without the blade guard as its a little dangerous for the un-initiated. A second hand one will be more than fine.
