just dont break them anyway , not really a problem as long as you dont use it head down go across the grass/lawn not up n down it as they are splash lubed not an oil pump so as long as its full should be allgood , just dont push the limits too far or for too long . still a lot to be said for a 2T you can mow a ceiling if you could .
if your 4T smokes , stop and do it different if it dont , just take it eeeeeeeeeeeasy if you know your doing it wrong just dont do it for long . at least if its full of oil it will pick it up from side but not if used facing plug down hill
