"shame about the blower"?????........not really! anyone who spends such time,effort and money on any kind of engine and FAILS TO USE AN AIR FILTER is a complete knob..........
also, they were in America with a week to source another blower.....could have done a deal, and had it posted, and fitted and they would have been back in the "race"....

they didnt seem very "savvy" to me...........
