So he did this for the week or two of the exercise, and later when the 100hourly was carried out, it was found that the 'new' engine had to be scrapped, due dust abrasion / scouring in all 4 cylinders.

It had never been pointed out to him, that the use of the carby heat, delivers 'hot unfiltered' air, directly into the carby....complete with all present dust particles....and these dust / dirt particles at his 'low level' had 'done the deed' to the donk.

Just sayin' is all.....

Cheers

A value for money instructor there!
