I don't know what you get so riled up about.
I HAVE one of these ASV's myself with the Perkins in it.
It don't friggin matter what equipment an engine runs in.Any one can/will overheat if the rad gets clogged,new or not.
If you know your machine is prone to getting hot,then keep an eye on it.
THAT IS WHAT THE FRIGGIN GAUGE IS FOR,
When a operator desides to ignore that little gadget then don't be surpriced if the thing blows up.
I do mulch,altough not for a living, but i know when to back off when it gets to tough
for that engine.
Sure, whatever you say dude.
